OPA607IDBVR

The OPA607 and OPA2607 devices are decompensated general-purpose CMOS operational amplifiers with a minimum stable gain of 6V/V, featuring low noise of 3.8nV/√Hz and a gain-bandwidth product (GBW) of 50MHz. The OPAx607 devices offer low noise and high bandwidth, making them well-suited for general-purpose applications that require a good balance between cost and performance. The high-impedance CMOS inputs make the OPAx607 amplifiers suitable for connecting to sensors with high output impedance (e.g., piezoelectric sensors). The OPAx607 devices have a power-down mode with a maximum quiescent current of less than 1μA, making them suitable for portable battery-powered applications. The rail-to-rail output (RRO) of the OPAx607 devices can swing up to 8mV relative to the supply rails, maximizing the dynamic range. The OPAx607 is optimized to operate at low supply voltages as low as 2.2V (±1.1V) and up to 5.5V (±2.75V), and is rated for operation over a temperature range of –40°C to +125°C.
