Overview
The LTC2362CTS8 from Analog Devices Inc. is a high-performance, 12-bit serial sampling analog-to-digital converter (ADC) designed for compact, low-power, and high-speed systems. This ADC is part of the LTC2360/LTC2361/LTC2362 family and is available in an 8-lead TSOT-23 package. It offers a high sample rate-to-power ratio, making it ideal for applications requiring low power consumption and high sampling rates.
The device operates on a single supply voltage ranging from 2.35V to 3.6V and features a dedicated external reference input. It is known for its low noise performance with a signal-to-noise ratio (SNR) of 73dB and low power dissipation, typically 1.5mW at 100ksps. The LTC2362CTS8 also includes a sleep mode with a very low supply current of 0.1μA, enhancing its suitability for battery-operated systems.
