OPA2180QDGKRQ1

The OPA180-Q1 and OPA2180-Q1 operational amplifiers utilize TI's proprietary zero-drift technology, which can simultaneously provide low offset voltage (75μV) and achieve near-zero drift performance over time and temperature changes. These high-precision, low quiescent current micro operational amplifiers offer high input impedance and rail-to-rail output swing within 18mV of the supply rails. The input common-mode range includes the negative supply rail. Single or dual power supplies with a voltage range of 4V to 36V (±2V to ±18V) can be used. Both single-channel and dual-channel versions are available in a VSSOP-8 package. The single-package product (OPA180-Q1) is rated for a temperature range of -40°C to +125°C, while the dual-package (OPA2180-Q1) is rated for a temperature range of -40°C to +105°C.
