DESCRIPTION
The OPA843 provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using a high Gain Bandwidth (GBW), two gain-stage design, the OPA843 gives a medium gain range device with exceptional dynamic range. The “classic” differential input complements this high dynamic range with DC precision beyond most high-speed amplifier products. Very low input offset voltage and current, high Common-Mode Rejection Ratio (CMRR) and PowerSupply Rejection Ratio (PSRR), and high open-loop gain combine to give a high DC precision amplifier along with low noise and high 3rd-order intercept.

FEATURES
● HIGH BANDWIDTH: 260MHz (G = +5)
● GAIN BANDWIDTH PRODUCT: 800MHz
● LOW INPUT VOLTAGE NOISE: 2.0nV/√Hz
● VERY LOW DISTORTION: –96dBc (5MHz)
● HIGH OPEN-LOOP GAIN: 110dB
● FAST 12-BIT SETTLING: 10.5ns (0.01%)
● LOW INPUT OFFSET VOLTAGE: 300µV
● OUTPUT CURRENT: ±100mA

APPLICATIONS
● ADC/DAC BUFFER AMPLIFIER
● LOW DISTORTION “IF” AMPLIFIER
● ACTIVE FILTERS
● LOW-NOISE RECEIVER
● WIDEBAND TRANSIMPEDANCE
● TEST INSTRUMENTATION
● PROFESSIONAL AUDIO
● OPA643 UPGRADE
