- Part Models
- 1
- 1ku List Price
- Starting From $1.79
Part Details
- Supply voltage range: 2.6 V to 5.5 V
- Low power
1.2 mA + 2× excitation current
0.5 μA shutdown current - Low input bias current: ± 100 pA
- High CMRR: 120 dB
- Space savings: 16-lead, 3.0 mm × 3.0 mm × 0.55 mm LFCSP
- Excitation current
300 μA to 1300 μA range
Set with external resistor
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.
Applications
- Bridge and sensor drives
- Portable electronics
