OPA192 Operational Amplifier

Description :

The OPA192 family (OPA192, OPA2192, and OPA4192) is a new generation of 36-V, e-trim
operational amplifiers. These devices offer outstanding dc precision and ac performance,
including rail-to-rail input/output, low offset (±5 µV, typ), low offset drift (±0.2 µV/°C, typ), and 10MHz
bandwidth.

Unique features such as differential input-voltage range to the supply rail, high output current and high capacitive load drive of up to 1 nF, and high slew rate make the OPA192 a robust, high-performance operational amplifier for high-voltage industrial applications. The OPA192 family of op amps is available in standard packages and is specified from –40°C to +125°C.

AD8290 Datasheet PDF – CMOS Sensor Amplifier

Part Number : AD8290

Function : G = 50, CMOS Sensor Amplifier with Current Excitation

Package : 16-Lead LFCSP_UQ

Manufacturers : Analog Devices

Pinouts :

AD8290 datasheet

 

Description :

The AD8290 contains both an adjustable current source to drive a sensor and a difference amplifier to amplify the signal voltage. The amplifier is set for a fixed gain of 50. The AD8290 is an excellent solution for both the drive and the sensing aspects required for pressure, temperature, and strain gage bridges. In addition, because the AD8290 operates with low power, works with a range of low supply voltages, and is available in a low profile package, it is suitable for drive/sense circuits in portable electronics as well. The AD8290 is available in a lead free 3.0 mm × 3.0 mm ×0.55 mm package and is operational over the industrial temperature range of −40°C to +85°C.
