MCP3201T-CI/ST

Analog To Digital Converters (ADC) Overview

The MCP3201T-CI/ST is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Microchip Technology. It features a single pseudo-differential input, an on-chip sample and hold circuit, and an SPI-compatible serial interface. The device operates within a supply voltage range of 2.7V to 5.5V, supporting maximum sampling rates of 100 ksps at 5V and 50 ksps at 2.7V. It is housed in an 8-pin TSSOP package and functions across an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with ±1 LSB maximum Differential Nonlinearity (DNL) and ±2 LSB maximum Integral Nonlinearity (INL).
• SPI serial interface compatible with modes 0,0 and 1,1.
• Low-power operation with typical standby current of 500 nA and maximum active current of 400 µA at 5V.

Analog To Digital Converters (ADC) Applications

• Sensor Interface
• Process Control
• Data Acquisition
• Battery Operated Systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'ST' corresponds to the TSSOP package variant when sourcing. Confirm that the 'CI' designation aligns with the required industrial temperature range (-40°C to +85°C). Ensure compatibility with standard SPI protocols for system integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a single-channel, low-power ADC with moderate speed. Verify that the source impedance driving the IN+ pin is sufficiently low to maintain linearity specifications during the 1.5 clock cycle sampling period. Consider the 2.7V minimum supply voltage for battery-powered designs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP3201 family of 12-bit A/D converters. The 'T' suffix indicates tape and reel packaging, while 'ST' specifies the 8-pin TSSOP package. The 'CI' suffix denotes the industrial temperature grade. Other variants include MSOP, PDIP, and SOIC packages.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must match the 12-bit resolution, SPI interface, and TSSOP-8 package. Verify pinout compatibility and electrical characteristics such as supply voltage range and sampling rate against the original specification requirements.
