DESCRIPTIO
700MHz Gain Bandwidth ± 200m A Minimum IOUT Low Distortion:
- 72d Bc at 1MHz, 4VP-P, 25Ω, AV = 2 Stable in AV ≥ 10, Simple pensation for AV < 10 ± 4.3V Minimum Output Swing, VS = ± 6V, RL = 25Ω 7m A Supply Current per Amplifier 200V/µs Slew Rate Stable with 1000p F Load 6n V/√Hz Input Noise Voltage 2p A/√Hz Input Noise Current 4m V Maximum Input Offset Voltage 4µA Maximum Input Bias Current 400n A Maximum Input Offset Current ± 4.5V Minimum Input CMR, VS = ± 6V Specified at ± 6V, ± 2.5V
The LT®1886 is a 200m A minimum output current dual op amp with outstanding distortion performance. The amplifiers are gain-of-ten stable, but can be easily pensated for lower gains. The LT1886 Features balanced, high impedance inputs with 4µA maximum input bias current, and 4m V maximum input offset voltage. Single supply applications are easy to implement and have lower total noise than current feedback amplifier implementations. The output drives a 25Ω load to ±4.3V with ±6V supplies. On ±2.5V supplies the output swings ±1.5V with a 100Ω load. The amplifier is stable with a 1000p F capacitive load which makes it useful in buffer and cable driver applications. The LT1886 is manufactured on Linear Technology’s advanced low voltage plementary bipolar process and is available in a thermally enhanced SO-8 package.
