MCP3302-BI/P

Analog To Digital Converters (ADC) Overview

The MCP3302-BI/P is a 13-bit Analog-to-Digital Converter (ADC) manufactured by Microchip Technology. It features full differential inputs and supports two differential or four single-ended input channels. The device utilizes a successive approximation architecture with an on-board sample-and-hold circuit, communicating via an industry-standard SPI serial interface. It operates within a supply voltage range of 4.5V to 5.5V, achieving sampling rates up to 100 ksps at 5V. Key electrical specifications include ±1 LSB maximum Differential Nonlinearity (DNL) and Integral Nonlinearity (INL). The component is housed in a 14-pin PDIP package and is designed for industrial temperature ranges.

Analog To Digital Converters (ADC) Feature Summary

• 13-bit resolution with ±1 LSB maximum DNL and INL
• Configurable for 2 differential or 4 single-ended inputs
• SPI serial interface compatible with PIC microcontrollers
• Low power consumption: 50 nA typical standby current

Analog To Digital Converters (ADC) Applications

• Remote sensors
• Battery-operated systems
• Transducer interface

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BI' against the official datasheet to confirm B-grade accuracy specifications. Ensure the PDIP-14 package matches the design requirements. Confirm that the operating environment falls within the specified -40°C to +85°C industrial temperature range. Validate that the system supply voltage remains strictly between 4.5V and 5.5V for guaranteed performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high linearity is required, as indicated by the ±1 LSB INL specification. It is suitable for applications needing differential input configurations to reject common-mode noise. Consider the 100 ksps sampling rate capability if higher throughput than lower-resolution ADCs is needed. Ensure the host microcontroller supports the required SPI clock frequencies up to 2.1 MHz.

Analog To Digital Converters (ADC) Part Context

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