LTC1865IMS

The LTC1865IMS is a precision analog-to-digital converter (ADC) from Linear Technology (now Analog Devices). The “IMS” suffix indicates a specific package/lead-frame option; check the datasheet for exact pinout and package dimensions. It targets high-precision data acquisition and instrumentation, offering low noise and low offset with a serial interface that is SPI-compatible for easy integration with microcontrollers or FPGAs.
Key points:
- SPI-compatible serial interface for reading conversion results.
- Suitable for instrumentation, sensors, and DAQ systems requiring accurate digitization.
- Reference options: internal or external (as defined per variant); input range selections as per device family.
- Power management and stability features typical of precision ADCs (details in the data sheet).
Basic usage (conceptual):
- Apply the analog input to Vin+ and Vin−, and configure the reference.
- Supply the device and clock it to initiate conversions.
- Read the digital result via the SPI-compatible bus.
For exact performance specs, pinout, and package details, see the LTC1865IMS datasheet and related application notes.

LTC1865IMS features (concise):
- 8-channel, multiplexed 12-bit SAR ADC
- SPI-compatible serial interface for data readout
- Single-ended or differential inputs via on-chip multiplexer
