Linear Technology LTC2327-18 Input ADC Datasheet

About this manual

The LTC2327-18 is an 18-bit successive approximation register (SAR) analog-to-digital converter featuring pseudo-differential inputs. It operates from a single 5V supply and supports true bipolar input ranges of +6.25V, +10.24V, and +12.5V, making it suitable for high voltage applications requiring wide dynamic range.

Key features include a throughput rate of 500ksps with no missing codes at 18 bits, typical signal-to-noise ratio (SNR) of 95dB, and guaranteed operation up to 125°C. The device includes an onboard single-shot capable reference buffer with low drift (20ppm/°C max) and a SPI-compatible serial interface supporting daisy-chain mode.
