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. Low input bias current op amps are critical for interfacing downstream electronics with sensors in applications from photodiodes, pH meters, or other electrometer-like functions.
ST has many precision op amps that fit this small signal conditioning range of applications.
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.
TSV52 micropower amplifiers feature a high merit factor
ST's TSV521, TSV522, TSV524 are single, dual, and quad rail-to-rail input and output single-supply amplifiers operating from 2.7 to 5.5 V and featuring a very low supply current per amplifier of 45 µA while providing a 1.15 MHz bandwidth. The TSV52 family provides upgraded performance relative to ST‘s general-purpose range of standard op amps for a variety of applications, for example, in the industrial, medical and consumer segments.
