LTC2364-16
16-Bit, 250ksps, Pseudo-
Differential Unipolar SAR
ADC with 94.7dB SNR
DESCRIPTION
The LTC®2364-16 is a low noise, low power, high speed
16-bit successive approximation register (SAR) ADC.
Operating from a 2.5V supply, the LTC2364-16 has a 0V
to VREF pseudo-differential unipolar input range with VREF
ranging from 2.5V to 5.1V. The LTC2364-16 consumes
only 3.4mW and achieves ±0.75LSB INL maximum, no
missing codes at 16 bits with 94.7dB SNR.
The LTC2364-16 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 250ksps
throughput with no cycle latency makes the LTC2364-16
ideally suited for a wide variety of high speed applications.
An internal oscillator sets the conversion time, easing exter-
nal timing considerations. The LTC2364-16 automatically
powers down between conversions, leading to reduced
power dissipation that scales with the sampling rate.
