LTC2315ITS8-12

The LTC2315ITS8-12 is a Linear Technology (Analog Devices) 12-bit analog-to-digital converter. It uses a serial (SPI-compatible) interface to deliver digitized data to a microcontroller or DSP. Packaged in the compact ITS8 8-pin package, it targets space- and power-constrained instrumentation and data-acquisition applications. The device integrates a sample-and-hold and a successive-approximation ADC, supports single-supply operation with an external reference, and offers low input-noise and fast conversion suitable for real-time monitoring. Typical uses include data acquisition, process control, portable instrumentation, and test equipment. For exact performance metrics (sampling rate, input range, power, number of channels, reference requirements) and pinout, consult the LTC2315ITS8-12 datasheet and product brief.

Direct equivalents aren’t pin-for-pin; closest cross-references are 12‑bit, 1–2 MSPS SPI SAR ADCs in 8‑pin packages, e.g. Analog Devices AD7820/AD7821 family; Texas Instruments ADS7820/ADS7821; Microchip MCP3201/MCP3202.
