The AD7680 is a 16-bit, fast, low power, successive approximation ADC. The part operates from a single 2.5 V to 5.5 V power supply and features throughput rates up to 100 kSPS. The part contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 7 MHz.The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and the conversion is also initiated at this point. There are no pipelined delays associated with the part.The AD7860 uses advanced design techniques to achieve very low-power dissipation at fast throughput rates. The reference for the part is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus the analog input range for the part is 0 to VDD. The conversion rate is determined by the SCLK frequency.PRODUCT HIGHLIGHTS First 16-bit ADC in a SOT-23 package. High throughput with low power consumption. Flexible power/serial clock speed management. The conversion rate is determined by the serial clock, allowing the conversion time to be reduced through the serial clock speed increase. This allows the average power consumption to be reduced when a power-down mode is used while not converting. The part also features a shutdown mode to maximize power efficiency at lower throughput rates. Power consumption is 0.5 μA max when in shutdown. Reference derived from the power supply. No pipeline delays.APPLICATIONS Process control Battery-powered systems: Personal digital assistants Medical instruments Mobile communications Instrumentation and control systems Remote data acquisition systems High speed modems Optical sensors

The MAX9205/MAX9207 serializers transform 10-bit-wide parallel LVCMOS/LVTTL data into a serial high-speed bus low-voltage differential signaling (LVDS) data stream. The serializers typically pair with deserializers like the MAX9206/MAX9208, which receive the serial output and transform it back to 10-bit-wide parallel data.The MAX9205/MAX9207 transmit serial data at speeds up to 400Mbps and 660Mbps, respectively, over PCB traces or twisted-pair cables. Since the clock is recovered from the serial data stream, clock-to-data and data-to-data skew that would be present with a parallel bus are eliminated.The serializers require no external components and few control signals. The input data strobe edge is selected by TCLK_R/F. Active-low PWRDN is used to save power when the devices are not in use. Upon power-up, a synchronization mode is activated, which is controlled by two SYNC inputs, SYNC1 and SYNC2.The MAX9205 can lock to a 16MHz to 40MHz system clock, while the MAX9207 can lock to a 40MHz to 66MHz system clock. The serializer output is held in high impedance until the device is fully locked to the local system clock, or when the device is in power-down mode.Both the devices operate from a single +3.3V supply, are specified for operation from -40°C to +85°C, and are available in 28-pin SSOP packages.ApplicationsAdd/Drop MultiplexersBackplane and Interconnect ApplicationsCell Phone Base Stations Digital Cross-ConnectsDSLAMNetwork Routers and Switches

The SSM2135 dual audio operational amplifier permits excel-lent performance in portable or low power audio systems, with an operating supply range of 4 V to 36 V or ±2 V to ±18 V. The unity-gain stable device has very low voltage noise of 5.2 nV/√Hz, and total harmonic distortion plus noise below 0.01% over normal signal levels and loads. Such characteristics are enhanced by wide output swing and load drive capability. A unique output stage1 permits output swing approaching the rail under moderate load conditions. Under severe loading, the SSM2135 still maintains a wide output swing with ultralow distortion. Particularly well suited for computer audio systems and portable digital audio units, the SSM2135 can perform preamplification, headphone and speaker driving, and balanced line driving and receiving. Additionally, the device is ideal for input signal conditioning in single-supply, Σ-Δ, analog-to-digital converter subsystems such as the AD1877. The SSM2135 makes an ideal single-supply stereo output amplifier for audio digital-to-analog converters (DACs) because of its low noise and distortion.The SSM2135 is available in an 8-lead plastic SOIC package and is guaranteed for operation over the extended industrial temperature range of −40°C to +85°C.

The DG201A and DG211 are normally closed, quadsingle-pole single-throw (SPST) analog switches. TheseCMOS switches can be continuously operated withpower supplies ranging from ±4.5V to ±18V. Maximguarantees that these switches will not latch up if thepower supplies are disconnected with input signals stillconnected.Both devices have guaranteed break-before-makeswitching. The DG201A differs from the DG211 primarilyin switching speeds. The DG201A has a maximumturn-off time of 450ns and a maximum turn-on time of600ns. The DG211 has a maximum turn-off time of500ns and a maximum turn-on time of 1000ns.Compared to the original manufacturer's products,Maxim's DG201A and DG211 consume significantlylower power making them better suited for portableapplications. Maxim has also eliminated the need forthe third (VL) power supply that is required for the operationof the original manufacturer's DG211.ApplicationsCommunication SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosPBX, PABXTest EquipmentWinchester Disk Drives
