LTC2369-18

18-Bit, 1.6Msps, Pseudo-

Differential Unipolar SAR

ADC with 96.5dB SNR

FEATURES

DESCRIPTION

The LTC^®2369-18 is a low noise, low power, high speed

18-bit successive approximation register (SAR) ADC.

Operating from a 2.5V supply, the LTC2369-18 has a 0V

1.6Msps Throughput Rate

2.5V Supply

The LTC2369-18 has a high speed SPꢁ-compatible serial

interface that supports 1.8V, 2.5V, 3.3V and 5V logic while

also featuring a daisy-chain mode. The fast 1.6Msps

throughput with no cycle latency makes the LTC2369-18

ideally suited for a wide variety of high speed applications.

nal timing considerations. The LTC2369-18 automatically

powers down between conversions, leading to reduced

power dissipation that scales with the sampling rate.
