The OPA861IDBVT from Texas Instruments is a single-channel transconductance amplifier — its output is a current proportional to the differential input voltage, not a voltage swing.
The 900 V/µs slew rate and 80 MHz gain-bandwidth product define the small-signal bandwidth. Input bias current is 1 µA; input offset voltage is 3 mV typical. Output current capability is 15 mA per channel.
The THS4215DRBT is a voltage-feedback amplifier with a similar slew rate (970 V/µs) and bandwidth (350 MHz), but it is not a transconductance amplifier. For a true transconductance replacement, the OPA861 itself is the primary option; no direct pin-compatible second source is listed.
The OPA861IDBVT has a slew rate of 900 V/µs.
The OPA861IDBVT uses a standard SOT-23-6 pinout. The exact pin functions (input, output, supply, ground) are defined in the TI datasheet; no alternate pin mapping is documented.
