MCP3001-I/P

Analog To Digital Converters (ADC) Overview

The MCP3001-I/P is a 10-bit Analog-to-Digital Converter (ADC) from Microchip Technology, housed in an 8-pin PDIP package. It utilizes a Successive Approximation Register (SAR) architecture with a single pseudo-differential input channel and an SPI-compatible serial interface. The device supports sampling rates up to 200 ksps at 5V and 75 ksps at 2.7V. Key electrical specifications include ±1 LSB maximum Integral Nonlinearity (INL) and Differential Nonlinearity (DNL). It operates on a single supply voltage ranging from 2.7V to 5.5V, featuring low power consumption with typical standby current of 5 nA and active current of 400 µA.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix '-I/P' corresponds to the Industrial temperature range (-40°C to +85°C) and the 8-pin Plastic Dual In-line Package (PDIP). Confirm that the specific revision matches the DS21293C datasheet requirements for your application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 10-bit ADC with low pin count is required. Ensure the microcontroller SPI port supports Mode 0,0 or Mode 1,1. Verify that the source impedance is low enough to charge the internal sample capacitor within the specified clock cycles to maintain linearity.

Analog To Digital Converters (ADC) Part Context

The MCP3001 is part of the MCP300X family, which includes variants with 2, 4, or 8 channels. The '-I/P' designation specifically identifies the industrial temperature grade and through-hole packaging, distinguishing it from surface-mount options like SOIC or TSSOP.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same package and pinout are limited due to the unique single-channel configuration. Consider the MCP3002, MCP3004, or MCP3008 if additional channels are needed, noting that these require different pin mappings.
