Operating from a 2.5V supply, the LTC2382-16 has a ±2.5V fully differential input range. The LTC2382-16 consumes only 6.5m W and achieves ±2LSB INL max, no missing codes at 16-bits and 92d B SNR. The LTC2382-16 has a high speed SPI-patible 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 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 1.25µs allows the use of extremely low power ADC drivers.
