Product details
Overview
MCP3004T-E/ST from Microchip Technology is a 10-bit successive-approximation analog-to-digital converter (ADC) with on-chip sample-and-hold, SPI serial interface, and four single-ended or two pseudo-differential analog input channels. It operates from 2.7V to 5.5V, delivers up to 200 ksps at 5V, and features ±1 LSB INL/DNL - used in sensor interface and battery-operated data acquisition systems.
For engineers reviewing the MCP3004T-E/ST datasheet, MCP3004T-E/ST pinout, MCP3004T-E/ST application, or MCP3004T-E/ST equivalent, key selection criteria include its TSSOP-14 automotive-grade packaging (-40°C to +125°C), SPI mode 0/1 compatibility, 5 nA standby current, and channel configuration flexibility for embedded sensing nodes.
Technical Context
The MCP3004T-E/ST implements a SAR architecture with 1.5-clock-cycle sampling initiated on the first rising SCLK edge after CS low assertion. Conversion completes in 10 clock cycles, with output data shifted MSB-first on DOUT's falling edges.
It supports programmable analog input modes: four independent single-ended channels (CH0–CH3) or two pseudo-differential pairs (CH0/CH1 and CH2/CH3), where IN− is limited to ±100 mV relative to VSS and IN+ ranges from IN− to VREF + IN−.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822IDR | 8-bit resolution, 200 ksps, 2.7V–5.25V supply, no pseudo-differential mode | Limited to lower-precision industrial controls; lacks IN− noise rejection capability | Select when 8-bit resolution suffices and board space favors SOIC-8; not drop-in compatible due to pinout and feature set differences |
| MCP3204-I/P | 12-bit resolution, 100 ksps max, PDIP-14 package, -40°C to +85°C only | Higher precision but slower; lacks AEC-Q100 qualification and automotive temperature range | Choose for lab-grade instrumentation where resolution > speed; requires layout change due to PDIP vs. TSSOP and different pin mapping |
Compared with ADS7822IDR and MCP3204-I/P, the MCP3004T-E/ST uniquely balances 10-bit precision, 200 ksps throughput, pseudo-differential noise rejection, and AEC-Q100 Grade 1 qualification - making it optimal for cost-sensitive, space-constrained automotive and industrial sensing nodes requiring verified reliability.

FAQ
What is the maximum SPI clock frequency supported by the MCP3004T-E/ST?
The MCP3004T-E/ST supports up to 3.6 MHz SCLK at VDD = 5V and 1.35 MHz at VDD = 2.7V. These frequencies enable the full 200 ksps sample rate at 5V. Operation below 10 kHz is discouraged, as insufficient clocking degrades INL performance - especially at elevated temperatures - due to sample capacitor charge leakage.
Does the MCP3004T-E/ST support true differential input mode?
No, the MCP3004T-E/ST supports only pseudo-differential input mode. In this mode, one channel (e.g., CH0) serves as IN+, while the adjacent channel (e.g., CH1) serves as IN−, which is restricted to ±100 mV around VSS. It does not support fully differential signaling with symmetrical ±VREF swing or dedicated differential input pins like true differential ADCs.
How is the reference voltage configured on the MCP3004T-E/ST?
The MCP3004T-E/ST uses an external reference applied to the VREF pin, which sets the full-scale input range. VREF must be between 0.25V and VDD. The LSB size equals VREF / 1024. For example, with VREF = 3.3V, LSB = 3.22 mV. Internal reference is not provided - the device relies entirely on externally sourced, stable VREF for accuracy.
What is the purpose of the CS/SHDN pin on the MCP3004T-E/ST?
The CS/SHDN pin on the MCP3004T-E/ST serves dual functions: when pulled low, it enables SPI communication and initiates conversion; when held high, it disables the serial interface and places the device into 5 nA standby mode. It must be driven high between conversions to ensure proper power-down and avoid bus contention.
Is the MCP3004T-E/ST pin-compatible with the MCP3008 series?
No, the MCP3004T-E/ST is not pin-compatible with the MCP3008. The MCP3004T-E/ST is a 14-pin TSSOP device with CH0–CH3, while the MCP3008 uses a 16-pin package (SOIC or PDIP) supporting CH0–CH7. Pin assignments differ significantly - for example, DGND is on pin 7 in MCP3004T-E/ST but pin 9 in MCP3008 - requiring PCB redesign for substitution.
