Key Features
- 13-bit resolution successive approximation ADC for high-accuracy multi-channel analog acquisition
- 4 differential or 8 single-ended input channels selectable per conversion for flexible signal routing
- Analog input voltage range of -5 V to +5 V supporting bipolar and single-supply sensor signals
- SPI-compatible serial interface for simple connection to microcontroller SPI buses
- Maximum conversion time of 6.19 µs enabling throughput suitable for moderate-speed data logging
- 16-pin PDIP through-hole package ideal for prototyping and small-volume production
Applications
The MCP3304-BI/P is used in multi-channel precision data acquisition systems where both differential and single-ended sensor signals, such as thermocouples, bridge sensors, and current-sense outputs, must be digitized on a shared SPI bus. Industrial process monitoring equipment and laboratory instrumentation benefit from its 13-bit resolution and bipolar ±5 V input range. Embedded data loggers connected to PIC or AVR microcontrollers use its flexible channel configuration to reduce BOM complexity compared to multiple single-channel ADC devices.

Frequently Asked Questions
How many channels does the MCP3304-BI/P support and can they be mixed between differential and single-ended inputs?
The MCP3304-BI/P provides 4 differential or 8 pseudo-differential single-ended input channels. Channel mode is selected per conversion via the SPI command word, so a system can read some inputs differentially for noise rejection and others single-endedly on the same device without hardware changes.
What conversion time does the MCP3304-BI/P achieve and how does this affect sampling rate in a multi-channel logger?
The MCP3304-BI/P completes a 13-bit conversion in a maximum of 6.19 µs at full SPI clock rate. Across all 8 single-ended channels, sequential scanning allows approximately 20 kHz total throughput, which is adequate for low-frequency industrial sensor acquisition, thermocouple logging, and slow strain-gauge measurements.
Can the MCP3304-BI/P measure bipolar sensor outputs directly without an external level-shift circuit?
Yes. The MCP3304-BI/P accepts analog input voltages from -5 V to +5 V when the reference and supply are set to 5 V. This bipolar input range lets the device digitize current-output sensors with negative swing, bridge transducers with a centered zero, and thermocouple amplifiers with negative offset, all without adding a level-shift op-amp stage.
Is the MCP3304-BI/P RoHS-compliant and what is its recommended alternative if a surface-mount package is required?
The MCP3304-BI/P is RoHS-compliant with a Pb-free designation and JESD-609 e3 code. For surface-mount assembly, Microchip offers the MCP3304 in a 16-pin SOIC package (MCP3304-BI/SL), which provides identical 13-bit ADC performance in a smaller 10.3 mm × 7.5 mm body compatible with standard pick-and-place SMT lines.
