MCP3204T-CI/ST

Analog To Digital Converters (ADC) Overview

The MCP3204T-CI/ST is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Microchip Technology. It features four programmable input channels and operates on a single supply voltage ranging from 2.7V to 5.5V. The device supports a maximum sampling rate of 100 ksps at 5V and 50 ksps at 2.7V, utilizing an SPI-compatible serial interface for communication. It includes an on-chip sample and hold circuit and is available in a 14-pin TSSOP package with an industrial operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Four input channels configurable as single-ended or pseudo-differential pairs
• SPI serial interface supporting modes 0,0 and 1,1
• Low power consumption with typical standby current of 500 nA

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 'CI/ST' corresponds to the Industrial temperature range (-40°C to +85°C) and the 14-lead Thin Shrink Small Outline Package (TSSOP). Confirm that the specific revision matches the DS21298E datasheet specifications before integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent analog inputs are required within a compact surface-mount footprint. Ensure the system clock frequency does not exceed 2 MHz at 5V operation. Verify that the source impedance connected to the analog inputs allows for adequate charge acquisition during the 1.5 clock cycle sampling period to maintain specified linearity.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP3204/3208 family of low-power, 12-bit A/D converters. While the MCP3208 provides eight channels, the MCP3204 offers four channels in a 14-pin package. The 'T' suffix indicates tape and reel packaging, suitable for automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The MCP3204-BI/ST serves as a higher precision alternative offering ±1 LSB max INL compared to the ±2 LSB specification of the CI variant. Both share identical pinouts and electrical interfaces.
