Key Features
- Ultra-low input bias current of 0.1 pA maximum, enabling accurate signal processing with high-impedance sources such as pH electrodes and photodiodes
- High CMRR of 115 dB typical and 85 dB minimum for superior common-mode noise rejection in instrumentation amplifier topologies
- Low input offset voltage of 300 µV maximum ensures minimal DC error in precision signal conditioning and sensor amplifier designs
- Single op-amp in 8-pin DIP package with internal frequency compensation for stable unity-gain operation without external components
Applications
The TLC2201ACP is ideal for precision signal conditioning of high-impedance sensors such as pH electrodes, piezoelectric transducers, and photodiode current amplifiers where its 0.1 pA bias current causes negligible offset error. Its 115 dB typical CMRR and 300 µV max offset voltage make it well suited for medical instrumentation front ends, precision weigh scale amplifiers, and industrial strain gauge bridges requiring stable DC accuracy over the full operating temperature range.

Frequently Asked Questions
How does TLC2201ACP's 0.1 pA input bias current benefit pH sensor interface designs?
pH electrodes present source impedances of 100 MΩ to 1 GΩ; with TLC2201ACP's maximum input bias current of 0.1 pA, the resulting voltage error is at most 0.1 pA × 1 GΩ = 100 µV—well below the 300 µV offset voltage spec. This makes TLC2201ACP suitable for high-impedance electrochemical sensors without a separate buffer stage or FET-input op-amp.
What common-mode rejection performance does TLC2201ACP provide in a differential measurement circuit?
TLC2201ACP specifies a minimum CMRR of 85 dB and a typical CMRR of 115 dB. At 85 dB minimum, a 10 V common-mode signal at the input is attenuated to roughly 56 µV referred to the output, which is adequate for 12-bit to 14-bit ADC precision in noisy industrial environments where power-line interference couples onto sensor leads.
Can TLC2201ACP operate from a single 5 V supply in a portable medical device?
Yes, TLC2201ACP is designed for single-supply operation and supports supply voltages from 4 V to 16 V (or ±2 V to ±8 V dual supply). From a 5 V single supply the output swings close to both rails, enabling full-span signal processing without a negative supply rail in portable ECG monitors, pulse oximeters, and glucometers operating from lithium coin cells or USB power.
For a precision weigh scale using a 350 Ω strain gauge bridge, does TLC2201ACP provide adequate noise and offset performance?
TLC2201ACP's 300 µV max input offset voltage and low broadband voltage noise make it suitable for strain gauge bridge amplification at moderate gain settings. A 350 Ω bridge with 2 mV/V sensitivity at 5 V excitation produces a 10 mV full-scale signal; at 100 V/V gain the 300 µV offset contributes 30 mV referred to output, which is within calibration range for a 12-bit weigh scale system. Higher precision designs may require external offset nulling.
