DESCRIPTION
16-Bit, 500ksps, Low Power
SAR ADC with Serial Interface
The LTC2382-16 is a low noise, low power, high speed
16-bit successive approximation register (SAR) ADC.
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 daisychain mode. The fast 500ksps
throughput with no cycle latency makes the LTC2382-16
ideally suited for a wide variety of high speed applica-
tions. An internal oscillator sets the conversion time,
easing external timing considerations. The LTC2382-16
automatically powers down between conversions, lead-
ing 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.
