Key Features
- Dual rail-to-rail input and output op-amp with 8 MHz GBW operating from 3 V to 5 V single supply for low-voltage designs
- Ultra-low input bias current of 1 nA maximum at 25°C with 60 dB minimum CMRR for precision sensor interface circuits
- Compact 8-pin SOIC package with internal frequency compensation, enabling easy PCB integration without external compensation networks
Applications
The TSV912ID is well-suited for portable consumer electronics, battery-powered instrumentation, and sensor signal conditioning where a 3 V to 5 V single-supply voltage-feedback amplifier with rail-to-rail swing is required. Its dual-channel architecture allows compact filtering, buffering, and amplification stages in a single 8-pin SOIC footprint. The low bias current and 78 dB typical CMRR also make it effective in medical wearable sensor front-ends and industrial measurement circuits.

Frequently Asked Questions
For a 3.3 V single-supply sensor front-end, what gain-bandwidth product does the TSV912ID deliver?
The TSV912ID provides an 8 MHz gain-bandwidth product when operating from a 3.3 V single supply, sufficient for audio-frequency amplification and low-frequency sensor signal conditioning up to several hundred kHz at moderate closed-loop gains. The rail-to-rail output swing maximizes dynamic range on constrained 3 V rails.
How does the TSV912ID's input bias current specification benefit high-impedance sensor designs?
With a maximum input bias current of 10 nA and a typical value of 1 nA at 25°C, the TSV912ID introduces negligible error when interfacing with high-impedance sensors such as pH electrodes or piezoelectric transducers, where source resistances can exceed 1 MΩ. This avoids the offset voltage errors that higher-bias amplifiers would introduce.
What common-mode rejection ratio does the TSV912ID guarantee, and why does it matter in differential measurement systems?
The TSV912ID specifies a minimum CMRR of 60 dB and a nominal of 78 dB, meaning common-mode interference signals are attenuated by at least 1000:1 relative to differential signals. In industrial sensor bridges or ECG amplifiers, this prevents 50 Hz/60 Hz mains noise from corrupting the small differential signal of interest.
Does the TSV912ID support a 5 V supply rail used in many legacy microcontroller systems?
Yes, the TSV912ID operates from a 5 V supply, and its rail-to-rail input and output capability allows the output voltage to swing within a few millivolts of both the 0 V ground and the 5 V rail. This makes it compatible with 5 V microcontroller ADC inputs without requiring additional level-shifting or supply rails.
