What are the key features of MCP6V64-E/ST?
- Auto-zero chopper architecture eliminates offset drift, achieving near-zero offset over temperature without trimming
- 120 dB minimum CMRR with 134 dB typical for superior rejection of common-mode interference in differential measurements
- Ultra-low input bias current of 50 fA maximum enabling use with high-impedance sensors and pH electrodes
- Rail-to-rail input and output swing on a 5.5 V supply maximizing dynamic range in single-supply designs
- Quad channel in a 14-pin TSSOP reducing board area versus four discrete amplifiers
What is MCP6V64-E/ST used for?
The MCP6V64-E/ST is used in precision measurement front-ends for wheatstone bridge sensors, load cells, and thermocouple amplifiers where the auto-zero architecture keeps offset below 5 µV and drift below 0.05 µV/°C over the -40°C to 125°C industrial range. Its 50 fA bias current makes it suitable for high-impedance electrochemical sensors and pH probes that would be loaded by conventional op-amp inputs. The quad package also enables multi-channel differential acquisition systems on a single compact TSSOP footprint, minimizing BOM count in data acquisition modules.

Frequently Asked Questions
How does the MCP6V64-E/ST auto-zero architecture maintain low offset over temperature compared to a conventional op-amp?
The MCP6V64-E/ST uses a chopper stabilization technique that continuously measures and corrects the internal offset at a sampling rate above 10 kHz, keeping the effective input offset voltage below 5 µV and its temperature drift below 0.05 µV/°C. A conventional bipolar op-amp with 1 mV initial offset may drift by 5 µV/°C, accumulating 500 µV error from -40°C to 85°C, whereas the auto-zero design holds that error under 6 µV across the same range.
What CMRR does the MCP6V64-E/ST guarantee, and why does this matter in industrial sensor measurements?
The MCP6V64-E/ST guarantees a minimum CMRR of 120 dB with a typical value of 134 dB, meaning a 1 V common-mode noise signal on the input produces less than 1 µV of differential error at the output. In industrial environments with 50 Hz or 60 Hz mains interference on sensor cables, this level of rejection prevents noise from masking millivolt-level bridge or thermocouple signals.
For which high-impedance sensor applications is the MCP6V64-E/ST 50 fA bias current critical?
The 50 fA maximum input bias current is critical for pH electrode interfaces, ion-selective sensor front-ends, and photodiode transimpedance amplifiers where source impedances exceed 100 MΩ. A 50 fA bias current through a 100 MΩ source creates only a 5 µV offset error, whereas a standard CMOS op-amp with 1 pA bias current would produce 100 µV error on the same source, degrading measurement resolution by 20x.
How many amplifier channels does the MCP6V64-E/ST provide, and what layout advantage does the 14-pin TSSOP offer?
The MCP6V64-E/ST integrates 4 independent chopper amplifier channels in a 14-pin TSSOP package with a body size of approximately 5 mm × 4.4 mm. Compared to using 4 separate single-channel op-amp SOT-23 packages requiring about 4 × 9 mm² = 36 mm², the TSSOP-14 occupies roughly 22 mm², reducing footprint by nearly 40 % and cutting the number of decoupling capacitors from 4 sets to 1 shared supply pair.
