Core Features & Advantages
The TLC2252AIDR delivers micropower dual-channel amplification with rail-to-rail I/O, 850μV max offset (A-Grade), and industry-leading 19nV/√Hz noise for its 35μA/channel power budget.
- Primary Function: Dual-channel micropower rail-to-rail CMOS operational amplifier optimized for battery-powered signal conditioning with high-impedance sensor interfaces.
- Advantages:
- Ultra-low 35μA/channel supply current — enables extended battery life in portable and remote-sensing applications while maintaining 200kHz GBW and 19nV/√Hz noise performance.
- A-Grade 850μV max offset — precision-grade input offset enables accurate small-signal measurement without calibration, 2x tighter than the standard TLC2252 (1.5mV).
- 1pA typical input bias current — near-zero loading on high-impedance sources such as piezoelectric transducers, pH electrodes, and photodiodes, preserving signal integrity.
Typical Application Scenarios
- Industry: Portable Medical / Industrial Sensing / Consumer Battery-Powered
- Equipment: Handheld monitors, remote sensors, piezoelectric transducer interfaces, ADC front-ends
- Use Cases:
- Piezoelectric sensor signal conditioning with pA-level bias current preserving charge sensitivity and 19nV/√Hz noise floor.
- Battery-powered handheld monitoring instruments requiring months of operation with rail-to-rail ADC interfacing.
- Remote pressure and temperature sensor front-ends in industrial IoT with 4–20mA loop or low-voltage ADC interfaces.
