HA-2850

Data Sheet September 1998 File Number 2844.4

470MHz, Low Power, High Slew Rate Operational Ampliﬁer

The HA-2850 is a wideband, high slew rate, operational ampliﬁer featuring superior speed and bandwidth characteristics. Bipolar construction, coupled with dielectric isolation, delivers outstanding performance in circuits with a closed loop gain of 10 or greater.

A 340V/µs slew rate and a 470MHz gain bandwidth product ensure high performance in video and wideband ampliﬁer designs. Differential gain and phase are a low 0.04% and

0.04 degrees respectively, making the HA-2850 ideal for video applications. A full ±10V output swing, high open loop gain, andoutstanding AC parameters, make the HA-2850 an excellent choice for high speed Data Acquisition Systems.

For military grade product, refer to the HA-2850/883 data sheet. Intersil AnswerFAX(321-724-7800) Document #3595.
