SOT-23 (DBV)-5-8.12 mm² 2.9 x 2.8
The design of the OPAx354-Q1 family of high-speed, voltage-feedback CMOS operational amplifiers is for video and other applications requiring wide bandwidth. These devices are unity-gain stable and can drive large output currents. Differential gain is 0.02% and differential phase is 0.09°. Quiescent current is only 4.9 mA per channel.
The OPAx354-Q1 family of operational amplifiers (op-amps) are optimized for operation on single or dual supplies as low as 2.5 V (±1.25 V) and up to 5.5 V (±2.75 V). Common-mode input range extends beyond the supplies. The output swing is within 100 mV of the rails, supporting wide dynamic range.
The single-supply version (OPA354A-Q1) is available in the tiny SOT–23-5 (DBV) package. The dual-supply version (OPA2354A-Q1) is available in the miniature VSSOP-8 (DGK) package and features completely independent circuitry for lowest crosstalk and freedom from interaction. The quad-supply version (OPA4354-Q1) is available in the TSSOP-14 (PW) package. The device specifications are for operation over the automotive temperature range of –40°C to +125°C.
