Overview
The LTC2324HUKG-12#TRPBF is a high-performance, quad-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This device is part of the Linear Technology product line, now integrated into Analog Devices. It is designed for applications requiring high speed, low noise, and simultaneous sampling of multiple channels.
Operating from a single 3.3V or 5V supply, the LTC2324-12 features differential inputs with an 8VP-P differential input range, making it ideal for applications that demand a wide dynamic range and high common mode rejection. The ADC achieves ±0.5LSB INL typical, no missing codes at 12 bits, and a signal-to-noise ratio (SNR) of 78dB.
