The OPA2313-Q1 dual-channel operational amplifier combines low power consumption with good performance. This enables it to be used in a wide range of applications, such as infotainment, engine control units, automotive lighting and more. The OPA2313-Q1 features rail-to-rail input and output (RRIO) swings, low quiescent current (50 µA, typical), wide bandwidth (1 MHz) and very low noise (25 nV/√Hz at 1 kHz), making it attractive for a variety of applications that require a good balance between cost and performance. Furthermore, low input bias current enables this device to be used in applications with megaohm source impedances.

The robust design of the OPA2313-Q1 provides ease-of-use to the circuit designer: unity-gain stability with capacitive loads of up to 150 pF, integrated RFI/EMI rejection filter, no phase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection (4-kV HBM).

The device is optimized for operation at voltages as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V), and is specified over the extended temperature range of –40°C to +125°C.
