DESCRIPTION
16-Bit, 1Msps, Low Power
SAR ADC with Serial Interface
The LTC2383-16 is a low noise, low power, high speed
16-bit successive approximation register (SAR) ADC.
Operating from a 2.5V supply, the LTC2383-16 has a
±2.5V fully differential input range. The LTC2383-16
consumes only 13mW and achieves ±2LSB INL max, no
missing codes at 16-bits and 92dB SNR.
The LTC2383-16 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 1Msps
throughput with no cycle latency makes the LTC2383-16
ideally suited for a wide variety of high speed applica-
tions. An internal oscillator sets the conversion time,
easing external timing considerations. The LTC2383-16
automatically powers down between conversions, lead-
ing to reduced power dissipation that scales with the
sampling rate.
32k Point FFT fS = 1Msps, fIN = 20kHz
