- 140 dB typical CMRR (112 dB minimum) rejects common-mode interference from power supply noise and ground loops
- Ultralow input bias current of 50 fA maximum suits high-impedance sensor interfaces such as pH electrodes and photodiodes
- Quad channel configuration in a 14-pin TSSOP reduces cost and board area per channel in multi-channel signal conditioning
- Extended temperature range (E grade) ensures reliable operation across -40°C to +125°C industrial environments
Applications
The MCP6V99-E/ST is designed for precision DC and low-frequency signal conditioning in industrial instrumentation, including bridge amplifiers for load cells and pressure sensors where sub-microvolt offset and 140 dB CMRR are required. Its zero-drift architecture ensures measurement stability over temperature extremes from -40°C to +125°C, making it ideal for process control transmitters and medical diagnostic equipment. The quad configuration in a TSSOP-14 package allows four independent amplifier channels to interface simultaneously with multi-electrode sensor arrays or multi-axis MEMS transducers.

Frequently Asked Questions
What makes the MCP6V99-E/ST a zero-drift amplifier, and how does that benefit precision measurement?
The MCP6V99-E/ST uses an auto-zero or chopper-stabilization architecture that continuously cancels its own input offset voltage, resulting in near-zero offset drift over temperature. This means that a strain-gauge or thermocouple amplifier built with the MCP6V99 maintains its calibration accuracy to within a few microvolts across the -40°C to +125°C temperature range, eliminating the periodic recalibration required by standard op-amps.
How does the 140 dB CMRR of the MCP6V99-E/ST protect sensor signals in electrically noisy industrial environments?
A 140 dB typical CMRR means the MCP6V99-E/ST attenuates common-mode interference such as 50 Hz or 60 Hz mains noise by a factor of 10,000,000 relative to the differential signal. In a Wheatstone bridge pressure sensor circuit, this suppresses millivolt-level mains coupling on long cable runs, ensuring that the 1 mV to 10 mV bridge output is not corrupted by electromagnetic interference from nearby motors, variable-frequency drives, or switching supplies.
Why is the MCP6V99-E/ST's 50 fA maximum bias current important for high-impedance sensors like pH electrodes?
A pH glass electrode presents an impedance of 10 MΩ to 1 GΩ. With a maximum bias current of 50 fA (0.00005 µA), the MCP6V99-E/ST introduces a voltage error of only 50 µV into a 1 GΩ source, compared to 50 mV for a standard op-amp with 50 nA bias current. This 1000× improvement in error is essential for pH, ion-selective electrode, and photodiode transimpedance amplifier circuits where source impedance exceeds 10 MΩ.
How many amplifier channels does the MCP6V99-E/ST integrate, and what packaging benefit does this provide?
The MCP6V99-E/ST integrates 4 independent zero-drift op-amp channels in a single 14-pin TSSOP package. Using one quad device instead of four single-channel amplifiers reduces the total component count by 3 ICs, cuts BOM cost by approximately 60%, and shrinks the PCB area dedicated to amplification by roughly 75%, which is advantageous in multi-channel data acquisition boards and compact handheld instruments.
