Demonstration circuit 1562B is an engineering tool to design and evaluate the LTC699X-X family of TimerBlox® circuits. The center section of the board contains a preconfigured TimerBlox function. DC1562B comes in twelve timing function variations as outlined in Table 1.

Demonstration circuit DC1641 is DC/DC boost converter featuring the LTC3786 constant frequency current mode boost controller. The DC1641A operates over 5V to 24V input and provides over 5A at 6V input voltage and over 9A of output current at 10V input as shown in figure 3. The 350kHz constant frequency operation results in small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.

Demonstration circuit DC1666A is a synchronous four-switch buck-boost LED driver controller. It accepts an input voltage from 4.7V to 60V, and drives up to 25V of LEDs at 2A. DC1666A features both PWM and analog dimming of the LED string. It has an OPENLED flag that indicates when the LED string has been removed and it has a SHORTLED flag that indicates that the output has been shorted to GND. In both cases, the IC remains in control and well protected.

The LTC5584 is a direct conversion quadrature demodulator optimized for high linearity receiver applications in the 30MHz to 1.4GHz frequency range. It is also usable in the 10MHz to 30MHz and 1.4GHz to 2GHz ranges with reduced performance. It is suitable for communications receivers where an RF signal is directly converted into I and Q baseband signals with bandwidth of 530MHz or higher. The LTC5584 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, high frequency quadrature phase shifter. In addition, the LTC5584 provides four analog control voltage interface pins for IIP2 and DC offset correction, greatly simplifying system calibration.The high linearity of the LTC5584 provides excellent spurfree dynamic range for the receiver. This direct conversion demodulator can eliminate the need for intermediate frequency (IF) signal processing, as well as the corresponding requirements for image filtering and IF filtering. These I/Q outputs can interface directly to channel-select filters (LPFs) or to baseband amplifiers.Applications LTE/W-CDMA/TD-SCDMA Base Station Receivers Wideband DPD Receivers Point-To-Point Broadband Radios High Linearity Direct Conversion I/Q Receivers Image Rejection Receivers

The LTC2758 is a dual 18-bit multiplying serial-input, current-output digital-to-analog converter. LTC2758A provides full 18-bit performance (INL and DNL of ?1LSB maximum) over temperature without any adjustments. 18-bit monotonicity is guaranteed in all performance grades. This SoftSpan? DAC operates from a single 3V to 5V supply and offers six output ranges (up to ?10V) that can be programmed through the 3-wire SPI serial interface or pin-strapped for operation in a single range.Any on-chip register (including DAC output-range settings) can be read for verification in just one instruction cycle; and if you change register content, the altered register will be automatically read back during the next instruction cycle.Voltage-controlled offset and gain adjustments are also provided; and the power-on reset circuit and CLR pin both reset the DAC outputs to 0V regardless of output range.Applications Instrumentation Medical Devices Automatic Test Equipment Process Control and Industrial Automation

The LTM8047 is an isolated flyback ?Module DC/DC converter. The LTM8047 has an isolation rating of 725VDC. For a similar product with LDO post regulator, see the LTM8048. Included in the package are the switching controller, power switches, transformer, and all support components. Operating over an input voltage range of 3.1V to 32V, the LTM8047 supports an output voltage range of 2.5V to 12V, set by a single resistor. Only output, input, and bypass capacitors are needed to finish the design. Other components may be used to control the soft-start control and biasing.The LTM8047 is packaged in a thermally enhanced, compact (11.25mm ? 9mm ? 4.92mm) over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8047 is available with SnPb (BGA) or RoHS compliant terminal finish.Applications Industrial Sensors Industrial Switches Ground Loop Mitigation

Demonstration circuit 1697A features the LTC2945. The LTC2945 is a rail-to-rail system monitor that measures current, voltage, and power. It features an operating range of 2.7V to 80V and includes a shunt regulator for supplies above 80V to allow flexibility in the selection of input supply. The current common mode measurement range of 0V to 80V is independent of the input supply. An onboard 0.75% accurate 12-bit ADC measures load current, input voltage and an auxiliary external voltage. A 24-bit power value is generated by digitally multiplying the measured 12-bit load current and input voltage data. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard I2C interface. The demo board is populated for a 5A application. This can be changed by populating R1 accordingly.

The LT1999 is a high speed precision current sense amplifier, designed to monitor bidirectional currents over a wide common mode range. The LT1999 is offered in three gain options: 10V/V, 20V/V, and 50V/V.The LT1999 senses current via an external resistive shunt and generates an output voltage, indicating both magnitude and direction of the sensed current. The output voltage is referenced halfway between the supply voltage and ground, or an external voltage can be used to set the reference level. With a 2MHz bandwidth and a common mode input range of ?5V to 80V, the LT1999 is suitable for monitoring currents in H-Bridge motor controls, switching power supplies, solenoid currents, and battery charge currents from full charge to depletion.The LT1999 operates from an independent 5V supply and draws 1.55mA. A shutdown mode is provided for minimizing power consumption.The LT1999 is available in an 8-lead SOP, an 8-lead MSOP (original pinout), or an 8-lead pinout option engineered for FMEA.Applications High Side or Low Side Current Sensing H-Bridge Motor Control Solenoid Current Sense High Voltage Data Acquisition PWM Control Loops Fuse/MOSFET Monitoring
