Texas Instruments  OPA2810IDCNT

The OPA2810 is a dual-channel, FET-input, voltage-feedback operational amplifier withlow input bias current. The OPA2810 is unity-gain stable with a small-signal unity-gain bandwidthof 105 MHz, and offers excellent DC precision and dynamic AC performance at a low quiescent current(IQ) of 3.6 mA per channel (typical). The OPA2810 is fabricated on TexasInstrument’s proprietary, high-speed SiGe BiCMOS process and achieves significant performanceimprovements over comparable FET-input amplifiers at similar levels of quiescent power. With again-bandwidth product (GBWP) of 70 MHz, slew-rate of 192 V/µs, and voltage low noise of6 nV/√Hz, the OPA2810 is well suited for use in a wide range ofhigh fidelity data acquisition and signal processing applications.

The OPA2810 is characterized to operate over a wide supply range of 4.75 V to 27 V, andfeatures rail-to-rail inputs and outputs. The OPA2810 amplifier delivers 75 mA of linear outputcurrent, suitable for driving optoelectronics components and analog-to-digital converter (ADC)inputs or buffering DAC outputs into heavy loads.

The OPA2810 is available in 8-pin SOIC, SOT23, and VSSOP packages and is rated to workover the extended industrial temperature range of –40°C to +125°C. TheOPA810 isa single-channel variant of this device, available in 8-pin SOIC and 5-pin SOT-23 and SC70packages.
