What are the key features of TLV9041IDCKR?
- 1.2 V minimum supply voltage enabling operation directly from a single alkaline or Li-ion cell in battery-powered designs
- 350 kHz gain-bandwidth product balancing AC performance and quiescent current consumption in low-power sensor interfaces
- 12 pA maximum input bias current eliminating the need for large compensation resistors in high-impedance sensing circuits
- 75 dB minimum CMRR reducing common-mode interference in differential signal conditioning and bridge amplifier configurations
What is TLV9041IDCKR used for?
The TLV9041IDCKR targets battery-powered IoT sensors, wearable health monitors, and portable instrumentation where supply voltage can drop as low as 1.2 V near end-of-battery discharge. Its 12 pA bias current and 350 kHz bandwidth suit pH sensing, thermocouple amplification, and photodiode transimpedance amplifier designs where leakage current errors are unacceptable. The compact 5-pin SOT-23 package minimizes board area in space-constrained wearables and coin-cell powered nodes.

Frequently Asked Questions
How low can the TLV9041IDCKR supply voltage go and why does that matter for battery-powered designs?
The TLV9041IDCKR operates from as low as 1.2 V, which is the end-of-life voltage of many alkaline and rechargeable cells. This allows the device to remain functional throughout the battery's entire discharge curve without a boost converter, extending system runtime and reducing BOM cost in wearables or remote sensors.
What is the input bias current specification of the TLV9041IDCKR and how does it affect high-impedance sensor interfaces?
The TLV9041IDCKR specifies a maximum bias current of 12 pA at 25°C, which causes less than 1 mV of error across even a 1 GOhm source impedance. This allows direct interfacing with high-impedance sources such as pH electrodes, piezoelectric sensors, and MEMS microphones without significant signal attenuation or DC offset.
What is the bandwidth of the TLV9041IDCKR and what signal processing tasks does it support at that bandwidth?
With a 350 kHz gain-bandwidth product, the TLV9041IDCKR supports audio-band amplification up to 20 kHz at gains of 10 V/V or higher, as well as low-frequency sensor signal conditioning in biomedical and environmental monitoring applications. It is not intended for RF or high-speed video, but fits most low-power analog front-end designs comfortably.
For a wearable ECG front end, how does the TLV9041IDCKR's CMRR specification reduce power-line interference?
The device achieves a minimum 75 dB CMRR, attenuating 50 Hz or 60 Hz power-line common-mode noise by more than 5600:1 relative to the differential signal. In a 3-lead ECG application with millivolt-level cardiac signals, this rejection level keeps power-line artifacts below the noise floor without requiring additional notch filtering.
