OPA860ID

The OPA860ID is a versatile Monolithic Component designed for wide-bandwidth systems, including high performance video, RF and IF circuitry. It includes a wideband, bipolar operational transconductance amplifier (OTA) and voltage buffer amplifier. The OTA or voltage-controlled current source can be viewed as an ideal transistor. Like a transistor, it has three terminals - a high impedance input (base), a low-impedance input/output (emitter) and the current output (collector). The OTA, however, is self-biased and bipolar. The output collector current is zero for a zero base-emitter voltage. AC inputs centered about zero produce an output current, which is bipolar and centered about zero. The transconductance of the OTA can be adjusted with an external resistor, allowing bandwidth, quiescent current and gain trade-offs to be optimized. Also included in the OPA860 is an uncommitted closed-loop, unity-gain buffer. This provides 1600MHz bandwidth and 4000V/µs slew rate.
