LTC1860CS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1860CS8#TRPBF is a 12-bit, 250ksps successive approximation analog-to-digital converter (ADC) in an 8-lead plastic SO package. It operates on a single 5V supply with a typical supply current of 850µA at full speed. The device features true differential analog inputs and an adjustable reference pin. It includes a sample-and-hold circuit and automatically powers down to a typical leakage current of 1nA between conversions. The part utilizes a 3-wire serial interface compatible with SPI/MICROWIRE standards for data transfer.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the CS8 designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the ordering information matches the manufacturer's current lead-free specifications and package drawings for the 8-lead SO format.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1860CS8#TRPBF for applications requiring a single-channel differential input ADC. Choose this model over the LTC1861 if a multiplexer is not required. Ensure the system design accommodates the external reference voltage requirement, as the reference pin is not internally tied to VCC in this variant. Verify source impedance constraints relative to the capacitive switching spikes.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1860/LTC1861 family of µPower, 12-bit sampling ADCs. It is pin-compatible with higher resolution 16-bit versions like the LTC1864 and LTC1865. The series is designed for compact, low-power systems where high speed-to-power ratios are critical. The SO-8 package offers a narrow footprint suitable for space-constrained designs.
