Key Features
- 8-channel delta-sigma ADC with 0.0032% max linearity error for high-precision multi-channel analog measurement
- Analog input range of 0.1 V to 3.7 V supports direct connection to low-level sensor outputs without additional signal conditioning
- Compact TSSOP-20 package enables high-channel-count data acquisition in space-constrained industrial PCBs
Applications
The MCP3464-E/ST is designed for precision data acquisition systems in industrial process control, environmental monitoring, and scientific instrumentation requiring 8 simultaneous analog channels with low linearity error. Its delta-sigma conversion topology provides inherent noise rejection, making it suitable for low-frequency, high-accuracy measurements such as temperature, pressure, and flow sensing. The TSSOP-20 package integrates 8 input channels in a small footprint, reducing BOM complexity in multi-sensor measurement platforms.

Frequently Asked Questions
How many analog input channels does the MCP3464-E/ST support and what is its maximum linearity error?
The MCP3464-E/ST provides 8 analog input channels and achieves a maximum linearity error of 0.0032%, which corresponds to less than 1 LSB of non-linearity at high resolution settings. This precision makes it appropriate for industrial weighing, precision temperature measurement, and scientific data logging where accurate multi-channel readings are critical.
What analog input voltage range is supported by the MCP3464-E/ST and which sensor types does it accommodate?
The MCP3464-E/ST accepts analog inputs from 0.1 V to 3.7 V, covering the output range of many low-voltage sensors including thermocouples with cold-junction compensation, 3.3 V RTD bridges, and resistive pressure sensors. For sensors producing sub-100 mV outputs, a front-end instrumentation amplifier can be added before the ADC inputs to bring signals within the 0.1 V to 3.7 V window.
For a compact 8-channel industrial data logger, why is the TSSOP-20 package of the MCP3464-E/ST a good fit?
The 20-pin TSSOP package with 0.65 mm lead pitch delivers all 8 input channels, SPI interface, and power pins in a PCB footprint of approximately 6.5 mm x 4.4 mm. This allows designers to place the MCP3464-E/ST close to the analog sensor cluster and route short, low-noise signal traces on compact industrial data logger boards operating from a single 3.3 V supply.
