Demonstration circuit DC1499A is a high efficiency step-down DC/DC converter featuring LTC3631 with internal high side and synchronous power switches that draws only 12μA quiescent current. It has a wide 4.5V to 45V input range and internal over voltage monitor capable of protecting the part through 60V surges. The jumper selectable output is up to 5V. LTC3631 can supply up to 100mA load current with a programmable peak current limit that provides a simple method for optimizing efficiency in lower current applications. With no compensation required, LTC3631 is easily configured with minimal components.

The LTC2391-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC. Operating from a single 5V supply, the LTC2391-16 supports a large ?4.096V fully differential input range, making it ideal for high performance applications which require maximum dynamic range. The LTC2391-16 achieves ?2LSB INL max, no missing codes at 16-bits and 94dB SNR (typ). The LTC2391-16 includes a precision internal reference with a guaranteed 0.5% initial accuracy and a ?20ppm/?C (max) temperature coefficient. Fast 250ksps throughput with no cycle latency in both parallel and serial interface modes makes the LTC2391-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2391-16 dissipates only 95mW at 250ksps, while both nap and sleep power-down modes are provided to further reduce power during inactive periods.Applications Medical Imaging High Speed Data Acquisition Digital Signal Processing Industrial Process Control Instrumentation ATE

The LTC2657 is a family of octal I2C 16-/12-Bit Rail-to-Rail DACs with Integrated 10ppm/?C Max Reference. The DACs have built-in high performance, rail-to-rail, output buffers and are guaranteed monotonic. The LTC2657-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7V to 5.5V supply. The LTC2657-H has a full-scale output of 4.096V with the integrated reference and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the full-scale output to 2 times the external reference voltage.The parts use a 2-wire I2C compatible serial interface. The LTC2657 operates in both the standard mode (maximum clock rate of 100kHz) and the fast mode (maximum clock rate of 400kHz). The LTC2657 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale at power-up. If PORSEL is tied to VCC, the DACs reset to mid-scale at power-up.Applications Mobile Communications Process Control and Industrial Automation Instrumentation Automatic Test Equipment Automotive

The LTC2382-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2382-16 has a ?2.5V fully differential input range. The LTC2382-16 consumes only 6.5mW and achieves ?2LSB INL max, no missing codes at 16-bits and 92dB SNR. The LTC2382-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisychain mode. The fast 500ksps throughput with no cycle latency makes the LTC2382-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2382-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate. The LTC2382-16 features a proprietary sampling architecture that enables the ADC to begin acquiring the next sample during the current conversion. The resulting extended acquisition time of 1.25?s allows the use of extremely low power ADC drivers.Applications Medical Imaging High Speed Data Acquisition Portable or Compact Instrumentation Industrial Process Control Low Power Battery-Operated Instrumentation ATE?
