Dual voltage-feedback op-amp with 250V/µs slew rate
The OPA2889IDGST is a dual-channel voltage-feedback operational amplifier from Texas Instruments, built for signal paths that need both speed and power efficiency. Its 250V/µs slew rate and 115 MHz -3dB bandwidth mean it can handle fast pulse edges and wideband analog signals without significant distortion — think video buffers, ADC drivers, or high-speed data acquisition front-ends.
115 MHz bandwidth, 920 µA per channel — the speed-efficiency trade-off
Each of the two amplifiers draws just 920 µA of supply current, which is remarkably low for a part with this gain-bandwidth product of 75 MHz. The 250V/µs slew rate means the output can swing several volts in tens of nanoseconds — useful when driving the input of a high-speed ADC or reconstructing a fast waveform. The 60 mA output current per channel gives enough drive for moderate capacitive loads or multiple downstream stages. Input offset voltage is 1.5 mV typical, and input bias current is 150 nA — both reasonable for a wideband amplifier, though not ultra-precision. The supply range spans 2.6 V to 12 V, so it works from a single 3.3 V or 5 V rail as well as split supplies up to ±6 V.
Industrial temperature range and surface-mount package
Rated for -40°C to +85°C operation, the OPA2889IDGST fits industrial control, test equipment, and outdoor telecom gear that sees temperature swings. It comes in a 10-VSSOP package — the 3 mm × 3 mm footprint keeps the board area small, which helps with signal routing in dense mixed-signal layouts. Surface-mount only; the tape-and-reel option suits automated assembly.
Active production, RoHS3 compliant
It is ROHS3 compliant, so it meets current EU and global restrictions on hazardous substances.
