Key Features
- Ultra-low quiescent current of 10 µA per channel from a 1.2 V minimum supply, extending battery life in always-on sensing and IoT endpoint designs
- Quad op-amp configuration with 350 kHz gain-bandwidth product and 89 dB typical CMRR, enabling four independent signal conditioning channels in a single package
- 12 pA maximum input bias current and 30 pA input offset current, supporting high-impedance piezo, photodiode, and electrochemical sensor interfaces without signal loading
Applications
The TLV9044IDYYR is optimized for energy-harvesting wearables, coin-cell powered environmental sensors, and IoT edge nodes where four analog signal paths must be amplified with minimal current drain. Its 1.2 V minimum supply allows operation directly from a nearly depleted Li battery or energy harvester output, extending deployment intervals in remote monitoring applications. The quad channel count also makes it cost-effective in multi-axis inertial sensor front ends and 4-channel transimpedance amplifier arrays for optical sensing.

Frequently Asked Questions
How low is the quiescent current of TLV9044IDYYR and what battery life benefit does this provide in a 4-channel design?
Each of the 4 op-amp channels in TLV9044IDYYR draws only 10 µA quiescent current, totaling 40 µA for the full quad device at 5.5 V supply. In a coin-cell-powered sensor node with a 220 mAh CR2032 battery, this 40 µA standby load alone contributes less than 0.5 mA-equivalent drain, allowing multi-year operation when combined with duty-cycled sensing firmware.
What is the minimum supply voltage for TLV9044IDYYR and how does this enable energy-harvesting designs?
The TLV9044IDYYR operates from as low as 1.2 V single supply, which is below the minimum output voltage of many solar-cell and thermoelectric energy harvesters. This 1.2 V threshold allows the op amp to remain functional even when the harvester output sags under low-light or low-temperature conditions, maintaining signal conditioning continuity in perpetually powered sensor systems without a secondary regulated rail.
What CMRR does TLV9044IDYYR achieve and how does it compare to typical low-power op amps in noise-sensitive applications?
The TLV9044IDYYR delivers a typical common-mode rejection ratio of 89 dB with a guaranteed minimum of 75 dB across the operating temperature range. Compared to general-purpose low-power op amps that often specify 60 dB to 70 dB CMRR, the 89 dB typical value provides an additional 19 dB to 29 dB of rejection for 50 Hz or 60 Hz interference in analog front ends for biomedical, environmental, and precision industrial measurements.
For a compact wearable PCB, what package does TLV9044IDYYR use and how many channels does it integrate?
The TLV9044IDYYR integrates 4 independent op-amp channels in a small-outline SOT-23-style package (DYYR suffix denotes a 3 mm x 3 mm or similar micro-package in tape-and-reel format). Fitting 4 channels in a single IC replaces 4 discrete single op-amps, saving approximately 60% to 70% of PCB area and solder joints, which is critical for wrist-worn health monitors and hearing aids constrained to boards under 10 mm x 10 mm.
