What are the key features of TSV912AID?
- 8 MHz gain-bandwidth product for wide-bandwidth amplification on a 5 V supply
- 1 pA typical input bias current for ultra-high-impedance sensor interfaces
- Rail-to-rail input and output for maximum dynamic range at low supply voltages
- 2.7 V to 5.5 V single-supply operation compatible with 3.3 V and 5 V systems
- 78 dB typical CMRR for accurate differential signal processing
- Dual channel in SOIC-8 reduces BOM and PCB area versus two discrete op-amps
What is TSV912AID used for?
The TSV912AID is ideal for buffering high-impedance biosensors, pH probes, and photodiode transimpedance stages where even picoamp-level input bias current would degrade accuracy. Its 8 MHz bandwidth and rail-to-rail swing support active anti-aliasing filters in portable ADC front ends operating from a 3.3 V Li-ion supply. The dual-channel SOIC-8 format also makes it a cost-effective solution for stereo audio signal paths and battery-monitoring voltage divider buffers in handheld instruments.

Frequently Asked Questions
How does the 1 pA typical input bias current of the TSV912AID benefit photodiode transimpedance amplifier designs?
With a typical input bias current of only 1 pA (maximum 10 pA), the TSV912AID introduces negligible DC offset across large feedback resistors — at 1 GΩ the error is merely 10 µV, far below the 3000 µV max input offset voltage. This allows the device to amplify nanoampere-scale photodiode currents in optical sensors and medical spectroscopy instruments without the bias-current-induced distortion seen with standard CMOS op-amps that specify bias currents in the nanoampere range.
Can the TSV912AID drive a 100 pF capacitive load at 3.3 V for a touch-screen controller interface?
The TSV912AID is specified for stable unity-gain operation into capacitive loads up to 100 pF at a 3.3 V supply, making it directly suitable as an output buffer between a DAC or sensor and a touch-screen controller input pin. Its 8 MHz gain-bandwidth product provides sufficient phase margin even with the capacitive load pole, and the rail-to-rail output allows the full 0 V to 3.3 V signal range to be transferred without clipping at either supply rail.
How does the TSV912AID compare with the TSV911 single-channel version for a dual-channel filter design?
Selecting the TSV912AID dual over two TSV911 singles saves one IC package footprint — the SOIC-8 dual occupies roughly 5 mm × 4 mm versus two SOT-23-5 singles at approximately 3 mm × 1.6 mm each — and reduces the bill of materials by one line item and one decoupling capacitor. Both devices share the same 8 MHz bandwidth, 1 pA bias current, and 2.7 V to 5.5 V supply specifications, so moving from two singles to the dual is a direct functional drop-in once the PCB layout is updated.
