OPA694 SBOS319C − SEPTEMBER 2004 − REVISED NOVEMBER 2004 Wideband, Low-Power, Current Feedback Operational Amplifier FEATURES D D D D D D D UNITY GAIN STABLE BANDWIDTH: 1.5GHz HIGH GAIN OF 2V/V BANDWIDTH: 690MHz LOW SUPPLY CURRENT: 5.8mA HIGH SLEW RATE: 1700V/µsec HIGH FULL-POWER BANDWIDTH: 675MHz LOW DIFFERENTIAL GAIN/PHASE: 0.03%/0.0155 Pb-FREE AND GREEN SOT23-5 PACKAGE DESCRIPTION The OPA694 is an ultra-wideband, low-power, current feedback operational amplifier featuring high slew rate and low differential gain/phase errors. An improved output stage provides ±80mA output drive with < 1.5V output voltage headroom. Low supply current with > 500MHz bandwidth meets the requirements of high density video routers. Being a current feedback design, the OPA694 holds its bandwidth to very high gains—at a gain of 10, the OPA694 will still provide 200MHz bandwidth. RF applications can use the OPA694 as a low-power SAW pre-amplifier. Extremely high 3rd-order intercept is provided through 70MHz at much lower quiescent power than many typical RF amplifiers. The OPA694 is available in an industry-standard pinout in both SO-8 and SOT23-5 packages. +5V APPLICATIONS D D D D D WIDEBAND VIDEO LINE DRIVER MATRIX SWITCH BUFFER DIFFERENTIAL RECEIVER ADC DRIVER IMPROVED REPLACEMENT FOR OPA658 VIN 75Ω OPA694 402Ω 75Ω VLOAD RG− 59 75Ω RELATED PRODUCTS SINGLES — OPA683 OPA684 OPA691 OPA695 DUALS OPA2694 OPA2683 OPA2684 OPA2691 OPA2695 TRIPLES — — OPA3684 OPA3691 OPA3695 QUADS — — OPA4684 — — ...
