LTC2383-16 16-Bit, 1Msps, Low Power SAR ADC with Serial Interface
FEATURES DESCRIPTION
n
1Msps Throughput Rate
The LTC®2383-16 is a low noise, low power, high speed n
±2LSB INL (Max)
16-bit successive approximation register (SAR) ADC. n
Guaranteed 16-Bit No Missing Codes
Operating from a 2.5V supply, the LTC2383-16 has a n
Low Power: 13mW at 1Msps, 13µW at 1ksps
±2.5V fully differential input range. The LTC2383-16 n
92dB SNR (Typ) at fIN = 20kHz
consumes only 13mW and achieves ±2LSB INL max, no n Guaranteed Operation to 125°C missing codes at 16-bits and 92dB SNR. n 2.5V Supply The LTC2383-16 has a high speed SPI-compatible serial n Fully Differential Input Range ±2.5V interface that supports 1.8V, 2.5V, 3.3V and 5V logic n External 2.5V Reference Input while also featuring a daisy-chain mode. The fast 1Msps n No Pipeline Delay, No Cycle Latency throughput with no cycle latency makes the LTC2383-16 n 1.8V to 5V I/O Voltages ideally suited for a wide variety of high speed applica tions. n SPI-Compatible Serial I/O with Daisy-Chain Mode An internal oscillator sets the conversion time, easing exter- n Internal Conversion Clock nal timing considerations. The LTC2383-16 automatically n 16-Pin MSOP and 4mm × 3mm DFN Packages powers down between conversions, lead ing to reduced power dissipation that scales with the sampling rate.
