What are the key features of TSX921IYLT?
- 10 MHz gain-bandwidth product with rail-to-rail input/output for maximum dynamic range in single-supply systems
- Ultra-low 0.0001 µA bias current at 25°C enabling accurate signal conditioning with high-impedance sensors
- Wide 4 V to 16 V supply voltage range in a miniature 5-pin SOT-23 package for portable and space-constrained designs
What is TSX921IYLT used for?
The TSX921IYLT is well suited for portable sensor interface circuits, battery-powered instrumentation, and precision signal conditioning where low bias current and rail-to-rail swing are essential. Its 10 MHz bandwidth and 72 dB CMRR make it effective in active filter stages, transimpedance amplifiers, and audio pre-amplification in handheld devices. The wide supply range from 4 V to 16 V allows it to operate directly from single-cell lithium or multi-cell alkaline battery stacks without external regulation.

Frequently Asked Questions
How does the TSX921IYLT's 0.0001 µA bias current benefit high-impedance sensor interfaces?
The TSX921IYLT's maximum bias current of 0.0001 µA at 25°C means it introduces less than 100 pA of error current into sensor nodes with source impedances up to 1 MΩ, resulting in offset voltage errors below 0.1 mV, which is critical for pH probes, photodiodes, and capacitive humidity sensors.
What supply voltage range does the TSX921IYLT support, and which battery chemistries are compatible?
The TSX921IYLT operates from 4 V to 16 V, covering a single-cell Li-ion discharge range of 3.0 V to 4.2 V when boosted, a 3-cell alkaline stack at 4.5 V, or a 12 V lead-acid battery, making it versatile across portable consumer, automotive accessory, and industrial sensor applications.
For an active low-pass filter design, what usable bandwidth does the TSX921IYLT provide?
With a 10 MHz gain-bandwidth product, the TSX921IYLT can implement active filter stages with cutoff frequencies up to approximately 1 MHz at a closed-loop gain of 10 V/V, or up to 3 MHz at unity gain, suitable for anti-aliasing filters ahead of 12-bit ADCs sampling at up to 5 Msps.
How compact is the TSX921IYLT package, and what does that mean for PCB layout?
The 5-pin SOT-23 package measures approximately 1.6 mm × 2.9 mm with a 0.95 mm pin pitch, occupying less than 5 mm² of PCB area, which is roughly 4× smaller than an SO-8 package and makes it practical for densely packed wearable or IoT sensor boards.
When is the TSX921IYLT a better fit than a standard bipolar op-amp for a single-supply design?
Because the TSX921IYLT is a CMOS voltage-feedback amplifier with rail-to-rail input and output, it can process signals spanning the full 4 V to 16 V supply range without clipping, whereas a standard bipolar op-amp typically loses 1 V to 2 V headroom at each rail, making the TSX921IYLT preferable in 5 V single-supply systems where full dynamic range is required.
