What are the key features of TLC4501AIDG4?
- Chopper-stabilized architecture achieving 40 µV maximum input offset voltage and 100 dB typical CMRR, enabling sub-millivolt measurement accuracy without external trimming
- 4.7 MHz gain-bandwidth product supporting audio-frequency and instrumentation amplifier stages from DC to tens of kilohertz on a single 5 V supply
- 60 fA maximum input bias current at 25°C enabling accurate signal conditioning of ultra-high-impedance sources such as ion-selective electrodes and piezoelectric sensors
What is TLC4501AIDG4 used for?
The TLC4501AIDG4 excels in precision DC measurement and signal conditioning applications where zero-drift performance is critical, including bridge sensor amplification, thermocouple cold-junction compensation, and industrial process control transmitters. Its 40 µV maximum offset voltage and chopper-stabilized architecture eliminate the need for manual trim potentiometers, reducing calibration cost in high-volume production. The 8-pin SOIC package integrates easily into data acquisition front ends requiring stable DC gain over temperature and extended operating life.

Frequently Asked Questions
How does the chopper-stabilized architecture of TLC4501AIDG4 improve DC accuracy compared to standard op amps?
Chopper stabilization continuously nulls the input offset voltage by switching the amplifier input between the signal and a reference at a high chopping frequency, typically above 50 kHz. This keeps the effective input offset below 40 µV over the full operating temperature range, compared to 500 µV to 5 mV for standard CMOS op amps with comparable noise specifications. The result is that TLC4501AIDG4 maintains sub-0.1 mV measurement accuracy in bridge and thermocouple circuits without laser-trimmed resistors or user calibration.
What precision signal sources benefit most from TLC4501AIDG4's 60 fA input bias current specification?
Ultra-high-impedance sources such as ion-selective electrodes (source impedance 1 GΩ to 10 GΩ), pH sensors, and piezoelectric transducers benefit most, because at 60 fA, the voltage error from bias current across a 10 GΩ source is only 0.6 mV. Standard bipolar op amps at 100 nA to 1 µA bias current would introduce 1 V to 10 V of error at the same impedance, completely swamping the signal. The 85 dB minimum CMRR further suppresses 50/60 Hz pickup common in high-impedance lab and medical measurement setups.
What bandwidth and gain stability does TLC4501AIDG4 offer for low-frequency instrumentation amplifier designs?
With a gain-bandwidth product of 4.7 MHz, a TLC4501AIDG4 configured for a closed-loop gain of 100 V/V has a -3 dB bandwidth of approximately 47 kHz, more than sufficient for audio-frequency and most DC transducer measurement chains. The chopper-stabilized architecture eliminates 1/f (flicker) noise below approximately 1 kHz, providing a flat noise floor down to DC. This makes it preferable to standard CMOS amplifiers in 4–20 mA process transmitter front ends and precision weigh-scale signal chains.
Is TLC4501AIDG4 suitable for single-supply 5 V designs in portable instrumentation?
Yes. The TLC4501AIDG4 is specified for a 5 V single supply and supports rail-to-rail input and output, allowing the common-mode input range to reach near 0 V and the output to swing close to both supply rails. For a 5 V battery-powered sensor node, this maximizes the usable output voltage range, reducing the effective input-referred noise compared to a non-rail-to-rail amplifier that loses 1 V to 2 V of headroom at each rail. The 100 dB typical CMRR ensures robust operation when ground potential shifts of up to tens of millivolts occur between sensor and digitizer.
