产品简介：

The OPA607 and OPA2607 devices are decompensated, minimum gain of 6 V/V stable, general-purpose CMOS operational amplifier with low noise of 3.8 nV/√ Hz and a GBW of 50 MHz. The low noise and wide bandwidth of the OPAx607 devices make them attractive for general-purpose applications which require a good balance between cost and performance. The high-impedance CMOS inputs make the OPAx607 devices an ideal amplifier to interface with sensors with high output impedance (for example, piezoelectric transducers).

The OPAx607 devices feature a Power Down mode with a maximum quiescent current of less than 1 μA, making the device suitable for use in portable battery-powered applications. The rail-to-rail output (RRO) of the OPAx607 devices can swing up to 8 mV from the supply rails, maximizing dynamic range.

The OPAx607 is optimized for low supply voltage operation as low as 2.2 V (±1.1 V) and up to 5.5 V (±2.75 V), and is specified over the temperature range of –40°C to +125°C.
