SBOS293B – DECEMBER 2003 – REVISED MARCH 2004  
Ultra-Wideband, Current-Feedback  
OPERATIONAL AMPLIFIER With Disable  
FEATURES  
APPLICATIONS  
●
GAIN = +2 BANDWIDTH (1400MHz)  
● VERY WIDEBAND ADC DRIVER  
● LOW-COST PRECISION IF AMPLIFIER  
● BROADBAND VIDEO LINE DRIVER  
● PORTABLE INSTRUMENTS  
● ACTIVE FILTERS  
● ARB WAVEFORM OUTPUT DRIVER  
● OPA685 PERFORMANCE UPGRADE  
●
GAIN = +8 BANDWIDTH (450MHz)  
● OUTPUT VOLTAGE SWING: ±4.2V  
● ULTRA-HIGH SLEW RATE: 4300V/µs  
● 3RD-ORDER INTERCEPT: > 40dBm (f < 50MHz)  
● LOW POWER: 129mW  
● LOW DISABLED POWER: 0.5mW  
The OPA695’s 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.  
DESCRIPTION  
The OPA695 is a very high bandwidth, current-feedback op  
amp that combines exceptional 4300V/µs slew rate and low  
input voltage noise to deliver a precision low cost, high  
dynamic range Intermediate Frequency (IF) amplifier. Opti-  
mized 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. Even higher bandwidth at  
lower gains gives a 1400MHz video line driver for high  
resolution RGB.
