Rail-to-rail input and output swings, low quiescent current (150 μA typically at 5 VS) combined with a wide bandwidth of 3 MHz, and very low noise (14 nV/√Hz at 1 kHz) make this device family very attractive for a variety of battery-powered applications that require a good balance between cost and performance.
The lowinput bias current supports applications with megaohm source impedances.
The robust design of the OPAx314-Q1 series provides ease-of-use to the circuit designer: unitygain stability with capacitive loads of up to 300 pF, an integrated RF and EMI rejection filter, no phase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection (4-kV HBM).
The device is optimized for low-voltage operation as low as 1.
8 V (±0.
9 V) and up to 5.
5 V (±2.
75 V), and is specified over the full extended temperature range of –40°C to +125°C.
