What are the key features of TLC2654C-14DR?
- Chopper-stabilized architecture eliminates DC offset drift over temperature for ultra-precision signal conditioning
- 125 dB typical common-mode rejection ratio (CMRR) with 110 dB minimum for exceptional differential signal accuracy
- Sub-picoampere input bias current of 0.06 nA at 25°C enabling high-impedance sensor interfaces without loading error
What is TLC2654C-14DR used for?
The TLC2654C-14DR is designed for precision instrumentation amplifiers, thermocouple signal conditioning, and bridge sensor interfaces where sub-nanovolt DC offset and ultra-low bias current are critical. Its chopper stabilization technique corrects for inherent amplifier offset and drift, making it ideal for weighing scales, medical pressure sensors, and precision data acquisition front-ends requiring stable measurements over extended periods. The 14-pin SOIC package supports multi-stage signal chain designs in industrial measurement and scientific instrumentation equipment.

Frequently Asked Questions
What makes chopper stabilization in TLC2654C-14DR superior to standard op-amp topologies for DC precision?
The chopper-stabilized architecture of TLC2654C-14DR continuously corrects its own input offset voltage by modulating, amplifying, and demodulating the input signal, effectively canceling DC offset and 1/f noise. This results in input offset voltage remaining below a few microvolts across the full operating temperature range, unlike standard op-amps where VOS can drift 10-50 µV/°C and cause significant measurement error in precision 0 V to 5 V sensor applications.
How does the 0.06 nA bias current of TLC2654C-14DR benefit high-impedance sensor interface designs?
With a maximum input bias current of 0.06 nA (60 pA) at 25°C, the TLC2654C-14DR imposes negligible loading on high-impedance sources such as pH electrodes, ion-selective sensors, and photodetectors with source impedances up to 100 MΩ. Even at 100 MΩ, the 0.06 nA bias current creates less than 6 mV of additional offset voltage, preserving measurement accuracy in precision instrumentation.
What CMRR does TLC2654C-14DR achieve and why does it matter in industrial sensor applications?
The TLC2654C-14DR achieves a typical CMRR of 125 dB with a guaranteed minimum of 110 dB. In industrial environments where 50 Hz or 60 Hz common-mode interference can exceed 1 V on thermocouple or bridge sensor leads, a 110 dB CMRR attenuates 1 V of common-mode noise to less than 3.2 µV at the differential output, maintaining sub-10 µV measurement resolution in 4-20 mA current loop and RTD temperature sensing applications.
For a precision weigh scale design, how does TLC2654C-14DR compare to a standard low-offset op-amp?
A standard low-offset op-amp typically has 25-100 µV initial offset and 0.5-2 µV/°C drift, introducing unacceptable zero-point errors over a 0°C to 50°C operating range in weigh scales requiring 0.01% full-scale accuracy. The TLC2654C-14DR's chopper stabilization keeps offset below a few microvolts across temperature, and its 0.06 nA bias current avoids loading the 350 Ω load cell bridge, delivering superior zero-stability for legal-for-trade and laboratory balance applications.
