2.3.3 OPA607

The OPAX607 is a decompensated (gain = 6 V/V stable), general-purpose complementary metal oxide semiconductor (CMOS) operational amplifier (op amp) that provides low noise of 3.8 nV/√Hz and a wide gain bandwidth of 50 MHz. The low noise and wide bandwidth of the OPAX607 make the device attractive for general-purpose applications that require a good balance between cost and performance. The high-impedance CMOS inputs make the OPAX607 an ideal amplifier to interface with sensors with large output impedance (for example, piezoelectric transducers).

The OPA607 features a power-down mode with a maximum quiescent current of less than 1 μA, making the device excellent for use in portable battery powered applications. The rail-to-rail output (RRO) of the OPA607 can swing up to 10 mV from the supply rails, enabling maximum dynamic range.

This op amp is optimized for low-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
