What are the key features of TLV27L1CDG4?
- Ultra-low quiescent current of 11 µA per channel extends battery life in energy-harvesting and portable systems
- Rail-to-rail output swing maximizes dynamic range when operating from low single-supply voltages
- 160 kHz gain-bandwidth product suitable for audio filtering and low-frequency sensor signal conditioning
- Wide 2.7 V to 16 V supply range covers single-cell battery through industrial 12 V rail applications
What is TLV27L1CDG4 used for?
TLV27L1CDG4 suits battery-powered sensor front-ends such as thermocouple amplifiers, photodiode transimpedance stages, and precision bridge-sensor buffers where quiescent current budgets are tight. Its rail-to-rail output enables full-scale ADC driving from a single 3.3 V rail in microcontroller-based data-acquisition systems. The device also serves in always-on monitoring circuits for industrial equipment where sub-milliamp standby power consumption is required.

Frequently Asked Questions
What quiescent current and bandwidth does TLV27L1CDG4 offer for low-power sensor designs?
TLV27L1CDG4 draws only 11 µA per channel of quiescent current and provides a 160 kHz gain-bandwidth product. This combination makes it well-suited for battery-operated sensor nodes where the op-amp must remain powered continuously but overall standby current must stay in the microamp range to achieve months-long battery life.
How does the rail-to-rail output of TLV27L1CDG4 improve ADC input accuracy in single-supply systems?
The rail-to-rail output stage of TLV27L1CDG4 swings within a few millivolts of both supply rails, allowing the amplifier to drive an ADC input across the full 0 V to 3.3 V or 0 V to 5 V reference span. Without rail-to-rail capability, usable signal range would be reduced by 200 mV to 500 mV, causing the ADC to lose effective resolution on codes near the supply limits.
For a 3.3 V single-supply photodiode transimpedance amplifier, is TLV27L1CDG4 appropriate?
Yes. TLV27L1CDG4 operates down to 2.7 V single supply, making it compatible with 3.3 V rails. Its 0.06 pA typical input bias current minimizes the DC offset error across high-value transimpedance feedback resistors in the 1 MΩ to 10 MΩ range, and its rail-to-rail output ensures the converted photocurrent signal can be read by a 3.3 V ADC without a level-shift stage.
When would a designer choose TLV27L1CDG4 over a faster op-amp in a multi-channel data logger?
When the measurement bandwidth requirement is below 160 kHz and each channel must add no more than 11 µA to system power, TLV27L1CDG4 is the preferred choice over faster op-amps drawing 300 µA to 1 mA per channel. A 16-channel temperature or pressure logger drawing only 176 µA total from the amplifier array can operate for over 1 year on a 1000 mAh battery without a power-cycling scheme.
