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.
The transconductance of both OTAs can be adjusted
between pin 5 and –V_CC by 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
power.
