The LT1221 is stable in a noise gain of 4 or greater. It Features reduced input offset voltage, lower input bias currents and higher DC gain than devices with parable bandwidth and slew rate. The circuit is a single gain stage that includes proprietary DC gain enhancement circuitry to obtain precision with high speed. The high gain and fast settling time make the circuit an ideal choice for data acquisition systems. The circuit is also capable of driving capacitive loads which makes it useful in buffer or cable driver applications. The LT1221 is a member of a family of fast, high performance amplifiers that employ Linear Technology Corporation’s advanced plementary bipolar processing. For unity-gain stable applications the LT1220 can be used, and for gains of 10 or greater the LT1222 can be used. , LTC and LT are registered trademarks of Linear Technology Corporation C-Load is a trademark of Linear Technology Corporation Summing Amplifier Large-Signal Response VS = ±15V f = 2MHz VIN = 10VP-P - TA02 U WU U WW W ABSOLUTE AXI U RATI GS (Note 1) Total...
