MCP3302T-CI/SL

Analog To Digital Converters (ADC) Overview

The MCP3302T-CI/SL is a 13-bit successive approximation register (SAR) analog-to-digital converter manufactured by Microchip Technology. It features full differential inputs and operates on a single supply voltage ranging from 4.5V to 5.5V for specified performance, with functional operation down to 2.7V. The device supports a maximum sampling rate of 100 ksps at 5V and utilizes an industry-standard SPI serial interface. Key electrical specifications include a maximum differential nonlinearity (DNL) of ±1 LSB and a maximum integral nonlinearity (INL) of ±2 LSB for the C-grade variant. Typical standby current is 50 nA, while maximum active current is 450 µA at 5V.

Analog To Digital Converters (ADC) Feature Summary

• 13-bit resolution with SAR architecture and on-board sample and hold circuitry
• Configurable as two differential input pairs or four single-ended inputs
• Maximum DNL of ±1 LSB and INL of ±2 LSB (C-grade)
• SPI serial interface compatible with PIC microcontrollers

Analog To Digital Converters (ADC) Applications

• Remote data acquisition systems
• Battery-operated portable instrumentation
• Transducer and remote sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging and 'SL' indicates the SOIC-14 package format. Confirm the 'CI' suffix aligns with the industrial temperature range (-40°C to +85°C) and C-grade linearity specifications. Ensure compatibility with the required PCB footprint for the 150 mil SOIC package.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 13-bit resolution with low power consumption is required for battery-powered applications. The C-grade specification provides ±2 LSB INL, which may be sufficient for cost-sensitive designs where B-grade precision is not mandatory. Verify that the source impedance allows for the required acquisition time at the desired clock frequency to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP3302/04 family of 13-bit A/D converters. The MCP3302 variant specifically offers two differential or four single-ended channels, whereas the MCP3304 provides eight channels. Both share the same SAR architecture and SPI interface but differ in pin count and channel configuration.

Analog To Digital Converters (ADC) Replacement Considerations

MCP3302-BI/SL: Offers improved linearity with ±1 LSB INL (B-grade). MCP3302-CI/P: Same electrical characteristics but in a PDIP-14 through-hole package.
