Dual CMOS Op-Amp features zero-drift operation.

Press Release Summary:



Operating from 2.65-5.5 V supply with 165 µA current consumption, Model S-89713 features input offset voltage of 10 µV max and input offset drift of ±0.1 µV/°C. Internal phase compensation does not require external capacitor, and input and output signals can cover full supply range since amplifier is made in CMOS. Housed in 8-pin SNT-8A or TMSOP-8 package, amplifier has typical common mode rejection ratio of 130 dB and gain bandwidth product of 240 kHz.

S-89713 Dual CMOS Op-Amp Has Instrumentation Amplifier Capabilities



NEU-ISENBURG, Germany, -- The dual CMOS Op-Amp S-89713 is extending Seiko Instruments Mini Analog Series as a new member with a bunch of outstanding parameters. The input offset voltage of this zero-drift amplifier is only a mere 10microV maximum because of the applied auto-zero operation. With this very low input offset and an almost negligible input offset drift of typical +/- 0.1microV/degreesC this amplifier lends itself to applications requiring high gain for very small signals. This can be output from sensors, precision resistance for measurement purposes (shunts), strain gauge or other measurement bridge and a multitude of other signal sources. The supply voltage range is 2.65V to 5.5V.

Since the amplifier is made in CMOS, input- and output-signals can cover the full supply range. Current consumption is typically 165microA per Amplifier.
The internal phase compensation does not require an external capacitor. Other remarkable characteristics are the common mode rejection ratio (CMRR) of typical 130dB and the gain bandwidth product (GBP) of 240 KHz.

The dual amplifier die is packaged in an 8-pin package, either a SNT-8A of 2.0x2.5x0.5mm cubed or a TMSOP-8.
