Linear Technology LTC2326-18 Input ADC Datasheet

About this manual

The LTC2326-18 is a low noise, high speed 18-bit successive approximation register (SAR) ADC with pseudo-differential inputs. Operating from a single 5V supply, it features a +10.24V true bipolar input range, making it ideal for high voltage applications requiring a wide dynamic range.

Key features include a 250ksps throughput rate, guaranteed 18-bit no missing codes, and a 95dB SNR (typical) at 2kHz. The device includes an onboard single-shot capable reference buffer and a low drift (20ppm/°C max) 2.048V temperature compensated reference. It utilizes a high speed SPI-compatible serial interface supporting 1.8V to 5V logic voltages and features a daisy-chain mode.
