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 volt­age-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 volt­age. The OTAs provide a 250MHz large-signal band­width, 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 allowing bandwidth, quiescent current, harmonic dis­tortion and gain trade-offs to be optimized. The out­put 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 sepa­rately on within 30ns and off within 200ns at full power.

ELECTROSTATIC DISCHARGE SENSITIVITY
Any integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with ap­propriate precautions. ESD can cause damage ranging from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet published specifications.
Burr-Brown’s standard ESD test method consists of five 1000V positive and negative discharges (100pF in series with
1.5k) applied to each pin.
