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.
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.
