The OPA387, OPA2387, and OPA4387 ( OPAx387) family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the OPAx387 offset voltage and offset drift provide unparalleled long-term stability. With a mere 570 μA of quiescent current, the OPAx387 are able to achieve 5.7 MHz of bandwidth, a broadband noise of 8.5 nV/√Hz, and a 1/f noise at 177 nVPP. These specifications are crucial to achieve extremely-high precision and no degradation of linearity in 16-bit to 24-bit analog to digital converters (ADCs). The OPAx387 feature flat bias current over temperature; therefore, little to no calibration is needed in high input impedance applications over temperature.\n\nAll versions are specified over the industrial temperature range of –40°C to +125°C.

The OPA3875 offers a very wideband, 3-channel, 2:1 multiplexer in a small SSOP-16 package. Using only 11mA/ch, the OPA3875 provides three, gain of +2, video amplifier channels with greater than 400MHz large-signal bandwidth (4VPP). Gain accuracy and switching glitch are improved over earlier solutions using a new (patented) input stage switching approach. This technique uses current steering as the input switch while maintaining an overall closed-loop design. Gain matching between each of the 3-channel pairs is also significantly improved using this technique (<0.2% gain mismatch). With greater than 700MHz small-signal bandwidth at a gain of 2, the OPA3875 gives a typical 0.1dB gain flatness to greater than 150MHz. System power may be reduced using the chip enable feature for the OPA3875. Taking the chip enable line high powers down the OPA3875 to less than 900μA total supply current. Muxing multiple OPA3875 outputs together, then using the chip enable to select which channels are active, increases the number of possible inputs to the 3-channel outputs. Where a single channel of the OPA3875 is required, consider the OPA875.
