Key Features
- Quad rail-to-rail op-amp with 2 mV max input offset voltage and 74 dB typical CMRR for precision sensor signal amplification
- Ultra-low 0.01 pA bias current at 25 °C enabling accurate high-impedance source buffering in pH meters and electrochemical sensors
- TSSOP-14 package integrates 4 amplifier channels saving board space versus discrete single-channel solutions in compact designs
Applications
The TSV634AIPT is well suited for precision sensor front-end conditioning in portable medical instruments, industrial pressure transmitters, and battery-powered data loggers where low bias current and rail-to-rail swing are critical. Its quad channel configuration allows a single package to handle multiple sensor channels such as 4-wire bridge amplification, filter stages, and reference buffering simultaneously. The 53 dB minimum CMRR also helps reject common-mode noise in long-cable industrial measurement loops operating from 2.7 V to 5.5 V supplies.

Frequently Asked Questions
What is the input offset voltage specification of the TSV634AIPT, and how does it affect measurement accuracy in sensor circuits?
The TSV634AIPT has a maximum input offset voltage of 2000 µV (2 mV), which contributes a fixed DC error to the amplified output signal. For a gain of 100 V/V, this offset becomes 200 mV at the output, so designers should budget for offset trim or select a lower-offset variant when sub-millivolt accuracy is required in precision weigh-scale or thermocouple amplifier designs.
How low is the bias current of the TSV634AIPT, and what measurement applications benefit from this specification?
At 25 °C, the TSV634AIPT bias current is typically 0.00001 µA (10 fA), with a maximum of 0.0001 µA (100 fA), making it ideal for high-impedance source buffering in electrochemical sensors, pH probes, and photodiode current-to-voltage converters where even small bias currents would create unacceptable voltage errors across megaohm-range source impedances.
How many op-amp channels does the TSV634AIPT contain, and what package does it use?
The TSV634AIPT houses 4 independent voltage-feedback operational amplifier channels in a TSSOP-14 package with 14 pins on a 4.4 mm × 5 mm body. Placing all 4 channels in one package reduces PCB area and inter-channel wiring compared to using two dual-op-amp packages, simplifying layout in compact industrial or medical measurement boards.
What is the common-mode rejection ratio of the TSV634AIPT, and when does that matter in real designs?
The TSV634AIPT achieves a typical CMRR of 74 dB and a minimum of 53 dB, meaning common-mode interference signals are attenuated by at least 53 dB relative to differential input signals. This is particularly important in differential amplifier topologies used with bridge sensors or current-sense resistors in noisy industrial environments where 50 Hz or 60 Hz power-line interference couples symmetrically onto both inputs.
