OPA2662

Dual, Wide Bandwidth

OPERATIONAL TRANSCONDUCTANCE AMPLIFIER

FEATURES

● 370MHz BANDWIDTH

DESCRIPTION

The OPA2662 is a versatile driver device for ultra

wide-bandwidth systems, including high-resolution

video, RF and IF circuitry, communications and test

equipment. The OPA2662 includes two power volt-

age-controlled current sources, or operational

transconductance amplifiers (OTAs), in a 16-pin DIP

or SOL-16 package and is specified for the extended

industrial temperature range (–40°C to +85°C). The

output current is zero-for-zero differential input volt-

age. The OTAs provide a 250MHz large-signal band-

width, a 58mA/ns slew rate, and each current source

delivers up to ±75mA output current.

● 58mA/ns SLEW RATE

● HIGH OUTPUT CURRENT: ±75mA

● 400Mbit/s DATA RATE

● VOLTAGE-CONTROLLED CURRENT

SOURCE

● ENABLE/DISABLE FUNCTION

APPLICATIONS

The transconductance of both OTAs can be adjusted

between pin 5 and –V_CCby an external resistor,

allowing bandwidth, quiescent current, harmonic dis-

tortion and gain trade-offs to be optimized. The out-

put current can be set with a degeneration resistor

between the emitter and GND. The current mirror

ratio between the collector and emitter currents is

fixed to three. Switching stages compatible to logic

TTL levels make it possible to turn each OTA sepa-

rately on within 30ns and off within 200ns at full
