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 daisy-chain mode. The fast 500ksps throughput with no cycle latency makes the LTC2382-16 ideally suited for a wide variety of high speed applicat­ ions. An internal oscillator sets the conversion time, easing external timing considerations. The LTC...
