Overview
The LTC2335HLX-18#PBF is an 18-bit, low noise, 8-channel multiplexed successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC2335 series and is known for its high precision and flexibility. It operates from a 5V low voltage supply and can be configured to accept various input voltage ranges on a per-channel basis, including ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V. The ADC features an internal 2.048V reference and a 2× buffer, which simplifies its operation and enhances its signal-to-noise ratio (SNR).
