ST's low input bias current op amps are the perfect fit for any application where small differences in the current or voltage at the input of the op amps needs to be measured accurately. They are critical for interfacing downstream electronics with sensors in applications from photodiodes, pH meters, or other electrometer-like functions.
ST offers a large diversity of operational amplifiers featuring low and ultra-low input bias current, which fit this small signal conditioning range of applications.

High bandwidth Chopper Op Amps for automotive and industrial applications
Featuring very high-accuracy and stability (VIO ≤ 25 µV at 25 °C), our TSZ18 series of 5 V zero-drift op amps are ideal for high-accuracy, high-bandwidth sensor interfaces including body-signal monitors, blood-glucose meters, industrial sensors, factory automation, and low-side current sensing. Available in single-channel TSZ181 (1.2 x 1.3 mm DFN6 package) and dual-channel TSZ182 (2 x 2 mm DFN8 package) versions.
With an extended operating range of –40 to +150°C, TSZ181H and TSZ182H are ideal for harsh automotive environments.
The TSZ182H1 operates over an extended range of -40 to +175°C and features an ultra-low input bias current making the device ideal for high-accuracy high-bandwidth sensor interfaces for automotive environment.
TSV7 series: excellent precision (200 µV), low-power (10 µA or 60 µA)
The TSV711, TSV712, TSV714, TSV731, TSV732, TSV734 series of single-, dual-, and quad-channel operational amplifiers offers low-voltage operation (1.5 to 5.5 V), rail-to-rail inputs and outputs, and an excellent accuracy (V IO lower than 200 μV at 25 °C). Housed in the smallest industrial packages, these low-power devices benefit from ST’s 5 V CMOS technology and offer an excellent speed/power consumption ratio associated with an ultra-low input bias current.
These characteristics make the TSV7 series ideal for sensor interfaces and active filtering for battery-powered applications in the wearable, portable consumer, medical and industrial segments.

High bandwidth, low offset rail-to-rail Op Amps for Industrial and Automotive
Our new TSV791 and TSV792 operational amplifiers offer a high gain-bandwidth product (GBW) of 50 MHz combined with excellent accuracy, which is provided by a maximum input voltage of 200 µV. This ensures high accuracy when amplifying small-amplitude input signals.
The TSV791 (single), TSV792 (dual) are also available in a SOT23-5 and Mini SO-8 package and can operate from 2.2 to 5.5 V in single supply. Fully specified on a 22 pF load and able to handle an output capacitor up to 1 nF, this Op Amps can also be used as an A/D converter input buffer.
Automotive grade version is also available both for TSV791 and TSV792.
