HA-2850
®
May 2003
FN2844.5
470MHz, Low Power, High Slew Rate
Operational Amplifier
Features
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.
• High Slew Rate . . . . . . . . . . . . . . . . . . . . . . . . . . 340V/µs
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, and outstanding AC parameters, make the HA-2850 an
excellent choice for high speed Data Acquisition Systems.
• Low Offset Voltage. . . . . . . . . . . . . . . . . . . . . . . . . 0.6mV
For military grade product, refer to the HA-2850/883 data
sheet.

3. Differential gain and phase are measured with a VM700A video tester, using a NTC-7 composite VITS.
4. RL = 1kΩ, VO = ±10V, 0V to ±10V for slew rate.
Slew Rate
5. Full Power Bandwidth guaranteed based on slew rate measurement using: FPBW = --------------------------- ; V PEAK = 10V .
2πV PEAK
6. Refer to Test Circuit section of data sheet.
7. VSUPPLY = ±10V to ±20V.
8. This parameter is not tested. The limits are guaranteed based on lab characterization, and reflect lot-to-lot variation.
9. See “Typical Performance Curves” for more information.

15. It is recommended that resistors be carbon composition and that
feedback and summing network ratios be matched to 0.1%.
16. SETTLING POINT (Summing Node) capacitance should be less
than 10pF. For optimum settling time results, it is recommended
that the test circuit be constructed directly onto the device pins.
A Tektronix 568 Sampling Oscilloscope with S-3A sampling
heads is recommended as a settle point monitor.
