LTC2391CLX-16#PBF

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.
