GENERAL DESCRIPTION

The ADA4862-3 (triple) is a low cost, high speed, internally

fixed, G = +2 op amp, which provides excellent overall

performance for high definition and RGB video applications.

The 300 MHz, G = +2, −3 dB bandwidth, and 750 V/μs slew

rate make this amplifier well suited for many high speed

applications. The ADA4862-3 can also be configured to

operate in gains of G = +1 and G = −1.

The ADA4862-3 is available in a 14-lead SOIC package and is

designed to work in the extended temperature range of −40°C

to +105°C.

With its combination of low price, excellent differential gain

(0.02%), differential phase (0.03°), and 0.1 dB flatness out to

65 MHz, this amplifier is ideal for both consumer and

professional video applications.

The ADA4862-3 is designed to operate on supply voltages as

low as +5 V and up to 5 V using only 5.3 mA/amp of supply

current. To further reduce power consumption, each amplifier

is equipped with a power-down feature that lowers the supply

current to 200 μA/amp. The ADA4862-3 also consumes less

board area because feedback and gain set resistors are on-chip.

Having the resistors on chip simplifies layout and minimizes the

required board space.
