What are the key features of TC7650CPD?
- Chopper-stabilized (auto-zero) architecture delivers near-zero offset voltage drift over temperature for precision DC signal conditioning
- 130 dB typical CMRR and 120 dB minimum CMRR reject common-mode noise in differential measurement applications
- Ultra-low 0.01 nA bias current at 25 °C minimizes errors when interfacing with high-impedance sensors and electrochemical cells
What is TC7650CPD used for?
TC7650CPD excels in precision instrumentation amplifiers, strain gauge bridges, and thermocouple signal conditioning circuits where offset voltage and drift must be minimised over a wide temperature range. Its chopper-stabilized architecture makes it ideal for DC-coupled weigh scales, medical sensor front-ends, and industrial process control loops requiring long-term measurement stability. The 14-pin PDIP package suits breadboard prototyping and through-hole production boards in laboratory and industrial equipment.

Frequently Asked Questions
How does the chopper-stabilization in TC7650CPD improve long-term DC accuracy compared to a standard op-amp?
The TC7650CPD uses an internal auto-zero chopper circuit that continuously samples and corrects its own offset voltage, achieving sub-microvolt offset drift over temperature. Conventional op-amps can drift 1–10 µV/°C, while TC7650CPD holds offset errors to near zero across its operating range, enabling precision DC amplification with less than 1 µV of accumulated error in applications such as weigh scales or thermocouple amplifiers operating at 25 °C to 85 °C.
What is the input bias current of TC7650CPD and why does it matter for high-impedance sensor interfaces?
TC7650CPD specifies a maximum bias current of 0.0004 µA (400 pA) and a typical value of only 0.01 nA (10 pA) at 25 °C. When driving the input from a 10 MΩ sensor source, this 10 pA bias current produces just 0.1 µV of additional input error, preserving the sub-microvolt accuracy of the chopper-stabilized amplifier in pH electrode, photodiode, and electrochemical sensor circuits.
Which industrial measurement applications benefit most from TC7650CPD's 130 dB CMRR?
A 130 dB CMRR means TC7650CPD attenuates common-mode interference by a factor of more than 3 million, making it highly effective in 4–20 mA current-loop receivers, strain gauge bridges, and RTD transmitters operating in electrically noisy environments near motors or switching power supplies. Even with 1 V of 50 Hz or 60 Hz common-mode noise on the inputs, the resulting differential error remains below 1 µV, preserving measurement integrity.
Is TC7650CPD still in production and what is the typical procurement lead time?
TC7650CPD remains in active production with a YTEOL (years to end-of-life) value of approximately 8 years and a typical factory lead time of 6 weeks. Designers can safely use it in new industrial and instrumentation products without near-term obsolescence risk, and the standard 14-pin PDIP-14 package is widely stocked by global distributors for immediate delivery.
