The ADuM1250/ADuM1251 are hot swappable digital isolators with non-latching, bidirectional communication channels that are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers.The ADuM1250 provides two bidirectional channels, supporting a complete isolated I2C interface. The ADuM1251 provides one bidirectional channel and one unidirectional channel for applications where a bidirectional clock is not required.Both the ADuM1250 and the ADuM1251 contain hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus.These isolators are based on the iCoupler® chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size, and power consumption advantages as compared to optocouplers. With the ADuM1250/ADuM1251, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I2C interface to be implemented in a small form factor.Applications Isolated I2C, SMBus, or PMBus interfaces Multilevel I2C interfaces Power supplies Networking Power over Ethernet Hybrid electric vehicle battery management

This serial link supports display panels from QVGA (320 x 240) up to XGA (1280 x 768), or dual-view WVGA (2 x 854 x 480).The embedded audio channel supports I2S up to 32 bits per sample and at a 192kHz sample rate. The embedded control channel forms a full-duplex, differential 100kbps to 1Mbps UART link between the serializer and deserializer. The host electronic control unit (ECU) or microcontroller (µC) resides either on the MAX9259 or on the MAX9260. In addition, the control channel enables ECU/µC control of peripherals in the remote side of the serial link through I2C/UART.Preemphasis and channel equalization extend the link length and enhance the link reliability. Spread spectrum is available to reduce EMI on the serial and parallel output data signals.

The MAX9268 deserializer utilizes Maxim's gigabit multimedia serial link (GMSL) technology. The MAX9268 deserializer features an LVDS system interface for reduced pin count and a smaller package, and pairs with any GMSL serializer to form a complete digital serial link for joint transmission of high-speed video, audio, and bidirectional control data. The MAX9268 allows a maximum serial payload data rate of 2.5Gbps for a 15m shielded twisted-pair (STP) cable. The deserializer operates up to a maximum output clock rate of 104MHz (3-channel LVDS) or 78MHz (4-channel LVDS). This serial link supports display panels from QVGA (320 x 240) to WXGA (1280 x 800) and higher with 24-bit color. The 3-channel mode outputs an LVDS clock, three lanes of LVDS data (21 bits), UART control signals, and one I²S audio channel consisting of three signals. The 4-channel mode outputs an LVDS clock, four lanes of LVDS data (28 bits), UART control signals, an I²S audio channel, and auxiliary control outputs. The three audio outputs form a standard I²S interface, supporting sample rates from 8kHz to 192kHz and audio word lengths of 4 to 32 bits. The embedded control channel forms a full-duplex, differential, 100kbps to 1Mbps UART link between the serializer and deserializer. An electronic control unit (ECU), or microcontroller (µC), can be located on the serializer side of the link (typical for video display), on the MAX9268 side of the link (typical for image sensing), or on both sides. In addition, the control channel enables ECU/µC control of peripherals on the remote side, such as backlight control, grayscale Gamma correction, camera module, and touch screen. Base-mode communication with peripherals uses either I²C or the GMSL UART format. In addition, the MAX9268 features a bypass mode that enables full-duplex communication using custom UART formats. The GMSL serializer driver preemphasis, along with the MAX9268 channel equalizer, extends the link length and enhances the link reliability.

Using an on-chip bridge-tied load mono headphone amplifier, the MAX9860 can output 30mW into a 32Ω earpiece while operating from a single 1.8V power supply. Very low power consumption makes it an ideal choice for battery-powered applications.The MAX9860's flexible clocking circuitry utilizes common system clock frequencies ranging from 10MHz to 60MHz, eliminating the need for an external PLL and multiple crystal oscillators. Both the ADC and DAC support sample rates of 8kHz to 48kHz in either synchronous or asynchronous operation. Both master and slave timing modes are supported.Two differential microphone inputs are available with a user-programmable preamplifier and programmable gain amplifier. Automatic gain control with selectable attack/release times and signal threshold allows maximum dynamic range. A noise gate with selectable threshold provides a means to quiet the channel when no signal is present. Both the DAC and ADC digital filters provide full attenuation for out-of-band signals as well as a 5th order GSM-compliant digital highpass filter. A digital side tone mixer provides loopback of the microphones/ADC signal to the DAC/headphone output.Serial DAC and ADC data is transferred over a flexible digital I²S-compatible interface that also supports TDM mode. Mode settings, volume control, and shutdown are programmed through a 2-wire, I²C-compatible interface.The MAX9860 is fully specified over the -40°C to +85°C extended temperature range and is available in a low-profile, 4mm x 4mm, 24-pin thin QFN package.Request S/W DriversApplicationsAudio AccessoriesAudio HeadsetsMobile PhonesPortable Navigation DeviceSmart PhonesVoIP Phones

The MAX9921 provides a single chip solution to interface two 2-wire Hall-effect sensors to a low-voltage microprocessor (µP). This device supplies and monitors the current drawn by two Hall-effect sensors, filters the sensed current level, and outputs the corresponding logic level.The MAX9921 includes input diagnostics and fault protection. These features allow the device to determine fault conditions such as open inputs, inputs shorted to the battery, and inputs shorted to ground. If the MAX9921 detects any of these conditions at either IN1 or IN2, the device shuts off the current to the corresponding input. The MAX9921 protects the Hall sensors from supply transients up to 60V at the BAT supply. Normal operating supply voltage ranges from 6V to 18V. If the battery voltage is out of range, the MAX9921 shuts off the current to the Hall sensors.The MAX9921 provides an 80µs blanking time following Hall sensor power-up or restart. The open-drain logic outputs are compatible with logic levels up to 5.5V.The MAX9921 is available in a small 10-pin µMAX® package and is specified over the -40°C to +125°C automotive temperature range.ApplicationsDoor ModulesElectric SunroofsPowered Lift Gate ControllersPowered Running BoardsSeat MoversSeatbelt BucklesWindow Lifters
