What are the key features of TLC2652AMJB?
- Chopper-stabilized architecture achieving 140 dB typical CMRR and sub-picoampere (0.06 pA) input offset current for ultra-precision DC amplification
- 0.5 µA maximum average input bias current enabling accurate signal conditioning of high-impedance sensors such as pH electrodes and ionization detectors
- 8-pin ceramic DIP package rated for military temperature range (-55°C to +125°C) providing hermetic protection in harsh aerospace and scientific instrument environments
What is TLC2652AMJB used for?
TLC2652AMJB is designed for precision DC signal conditioning in scientific instruments, medical analyzers, and calibration references where offset voltage drift below 1 µV/°C and sub-picoampere input currents are critical. Its 140 dB CMRR makes it ideal for bridge amplifier circuits in load cells, strain gauges, and thermocouple signal chains requiring common-mode rejection above 100 dB. The ceramic DIP package supports long-life military and aerospace data acquisition systems operating from -55°C to +125°C.

Frequently Asked Questions
What is the input offset current specification of TLC2652AMJB and why does it matter for high-impedance sensor interfaces?
TLC2652AMJB specifies a maximum input offset current of 0.06 pA at 25°C and an average maximum of 0.5 pA. For a 10 MΩ source impedance, 0.06 pA produces only 0.6 µV of voltage error, making it suitable for pH electrode amplifiers, picoampere current-to-voltage converters, and electrometer-grade circuits where competing standard op-amps with 10 nA bias current would generate 100 mV of error.
How does the chopper-stabilization architecture of TLC2652AMJB minimize DC offset drift compared to standard bipolar op-amps?
Chopper stabilization in TLC2652AMJB uses an internal auto-zero loop that samples and corrects the input offset voltage continuously at a chopper frequency. This reduces effective input offset drift to below 0.05 µV/°C over the -55°C to +125°C range, versus 5 µV/°C to 20 µV/°C typical for bipolar op-amps, enabling precision DC amplification in thermometer bridges and calibration standards.
For a Wheatstone bridge load cell amplifier requiring 120 dB rejection, does TLC2652AMJB meet the CMRR requirement?
TLC2652AMJB exceeds the requirement with a minimum CMRR of 120 dB and a typical value of 140 dB. At 120 dB, a 1 V common-mode signal produces only 1 µV of differential output error. For a 10 mV full-scale load cell output at 5 V bridge excitation, this level of CMRR ensures the common-mode power supply noise does not corrupt the measurement at 16-bit ADC resolution.
When is TLC2652AMJB in ceramic DIP preferred over an equivalent precision CMOS op-amp in a plastic SOIC package for aerospace designs?
TLC2652AMJB in ceramic DIP is specified for designs requiring MIL-STD-883 qualification, temperatures from -55°C to +125°C, and hermetic sealing against moisture permeation above 85% RH. Plastic SOIC packages absorb moisture and can delaminate under thermal cycling from -55°C to +125°C, causing solder joint failures in avionics and satellite electronics where ceramic DIP lifetime exceeds 20 years.
