DESCRIPTION
The OPA695 is a very high bandwidth, current-feedback op
amp that combines an exceptional 4300V/µs slew rate and a
low input voltage noise to deliver a precision, low-cost, high
dynamic range Intermediate Frequency (IF) amplifier.
Optimized for high gain operation, the OPA695 is ideally
suited to buffering Surface Acoustic Wave (SAW) filters in an
IF strip or delivering high output power at low distortion for
cable-modem upstream line drivers. At lower gains, a higher
bandwidth of 1400MHz is achievable, making the OPA695 an
excellent video line driver for supporting high-resolution RGB
applications.
The OPA695 low 12.9mA supply current is precisely trimmed
at +25°C. This trim, along with a low temperature drift, gives
low system power over temperature. System power may be
further reduced using the optional disable control pin. Leaving
this pin open, or holding it HIGH, gives normal operation. If
pulled LOW, the OPA695 supply current drops to less than
170µA. This power-saving feature, along with exceptional
single +5V operation and ultra-small SOT23-6 packaging,
make the OPA695 ideal for portable applications.
