Core Features & Advantages
The TLC2252CDR delivers the same micropower dual-channel rail-to-rail CMOS amplification as the TLC2252AIDR in a commercial-grade (0–70°C) version optimized for cost-sensitive volume production.
- Primary Function: Dual-channel micropower rail-to-rail CMOS operational amplifier for battery-powered signal conditioning with standard-grade (1.5mV max) offset accuracy.
- Advantages:
- 35μA/channel at 19nV/√Hz — industry-leading noise-to-power ratio in the micropower class, four times quieter than competing low-power CMOS amplifiers.
- 1pA typical input bias current — virtually zero loading on high-impedance piezoelectric and capacitive sensors, preserving signal integrity in ultra-low-current measurement paths.
- Cost-optimized commercial grade — 0–70°C specification and 1.5mV max Vos reduce test cost and die screening, making it the most economical TLC2252 variant for consumer and portable applications.
Typical Application Scenarios
- Industry: Consumer / Portable / Battery-Powered
- Equipment: Handheld monitors, portable medical devices, ADC front-ends, piezoelectric sensor interfaces
- Use Cases:
- Battery-powered handheld instrument front-ends requiring rail-to-rail output for maximum ADC dynamic range.
- Piezoelectric transducer signal conditioning with pA bias current and 19nV/√Hz noise in consumer electronics.
- Low-cost sensor interface circuits in consumer products where 1.5mV offset is acceptable and commercial temperature range suffices.
