DESCRIPTION
The
LTC
®
2382-16
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 daisy-chain mode. The fast 500ksps
throughput with no cycle latency makes the LTC2382-16
ideally suited for a wide variety of high speed applications.
An internal oscillator sets the conversion time, easing exter-
nal 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 archi-
tecture 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.
