Overview
The LTC2335HLX-16#PBF is a high-performance, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC2335 family and is characterized by its low noise, high speed, and flexible input configuration. It operates as an 8-channel multiplexed successive approximation register (SAR) ADC, making it suitable for a wide range of high-voltage applications requiring wide dynamic range.
The ADC features a SoftSpan™ interface, which allows for conversion-by-conversion control of the input voltage span on a per-channel basis. This flexibility enables the ADC to accept various signal ranges such as ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V on any channel. The device also includes an internal 2.048V reference and a 2× buffer, simplifying basic operation and allowing for the use of an external reference to increase the input range and signal-to-noise ratio (SNR).
