- Selectable bias mode allows tradeoff between quiescent power and bandwidth in one device
- 65 dB minimum CMRR with 80 dB typical for low-noise differential signal processing
Applications
TLC271ID is designed for precision low-power signal conditioning in battery-operated instruments and portable medical devices where minimizing current consumption is essential. The selectable bias mode lets designers trade off between low power and higher bandwidth within a single component, simplifying BOM management. Its ultra-low 0.06 nA bias current makes it excellent for pH electrodes, photodiodes, and other high-impedance transducer interfaces.

Frequently Asked Questions
How does the selectable bias mode of TLC271ID help in portable designs targeting sub-1 mA total supply current?
TLC271ID offers multiple bias modes that set quiescent current and bandwidth together. In the lowest bias setting, supply current can drop well below 1 mA while the device still processes signals in the audio and sub-audio range (below 10 kHz). This makes TLC271ID practical for battery-powered instruments running from a single 9 V cell for extended field use.
What CMRR performance does TLC271ID offer, and how does that benefit differential measurement circuits?
TLC271ID specifies 65 dB minimum and 80 dB typical common-mode rejection ratio. In a bridge sensor conditioning circuit with ±2.5 V common-mode swing, 65 dB CMRR limits the induced offset to roughly 1.4 mV, acceptable for 12-bit ADC inputs without additional gain stages or active common-mode rejection circuitry.
For a temperature sensor circuit using a thermistor above 10 MΩ, how does TLC271ID prevent measurement error from input loading?
With only 0.06 nA maximum input bias current at 25°C, TLC271ID introduces just 0.6 µV of voltage error across a 10 MΩ source impedance — negligible for most 12-bit or even 16-bit temperature measurement systems. Bipolar op-amps with 50 nA to 500 nA bias currents would introduce 500 µV to 5 mV errors across the same source, degrading accuracy significantly.
