低入力バイアス電流オペアンプ

Offering a very low offset voltage, an excellent speed/current consumption ratio, and 3 MHz gain bandwidth, the low-power, zero-drift TSZ181H operational amplifier is available in space-saving packages. Able to operate over an extended temperature range of -40 to +150°C, this miniature, ultra-precision and low quiescent current op amp is an ideal choice for high-accuracy, high-bandwidth sensor interfaces in automotive environment.

Featuring very high-accuracy and stability (V_IO ≤ 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 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.

The TSB952 is a high bandwidth (52 MHz), rail-to-rail output, 36 V operational amplifier designed to meet the demanding requirements of power supply and industrial applications.

Available in SO8 and DFN8 3x3 wettable flanks packages, the device features high-speed performance, low power consumption, and extended supply voltage operating range.

Our new TSV791,  TSV7292 and TSV792IY 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 and TSV792IY (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.
