Product Details

The LT1220 is a high speed operational amplifier with superior DC performance. The LT1220 features reduced input offset voltage, lower input bias currents and higher DC gain than devices with comparable 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 large capacitive loads which makes it useful in buffer or cable driver applications.

The LT1220 is a member of a family of fast, high performance amplifiers that employ advanced complementary bipolar processing. For applications with gains of 4 or greater the LT1221 can be used, and for gains of 10 or greater the LT1222 can be used for increased bandwidth.

Applications

  • Wideband Amplifiers
  • Buffers
  • Active Filters
  • Video and RF Amplification
  • Cable Drivers
  • 8-, 10-, 12-Bit Data Acquisition Systems
