LT1187

LT1187 Low Power Video Difference Amplifier FEATURES ■ Differential or Single-Ended Gain Block (Adjustable) ■ –3dB Bandwidth, AV = ±2: 50MHz ■ Slew Rate: 165V/µs ■ Low Supply Current: 13mA ■ Output Current: ±20mA ■ CMRR at 10MHz: 40dB ■ LT1193 Pin Compatible ■ Low Cost ■ Single 5V Operation ■ Drives Cables Directly ■ Output Shutdown ■ Available in 8-Lead PDIP and SO Packages APPLICATIONS ■ Line Receivers ■ Video Signal Processing ■ Cable Drivers ■ Tape and Disc Drive Systems DESCRIPTION The LT®1187 is a difference amplifier optimized for operation on ±5V, or a single 5V supply and gain ≥2. This versatile amplifier features uncommitted high input impedance (+) and (–) inputs, and can be used in differential or single-ended configurations. Additionally, a second set of inputs give gain adjustment and DC control to the difference amplifier. The LT1187’s high slew rate, 165V/ms, wide bandwidth, 50MHz, and ±20mA output current require only 13mA of supply current. The shutdown feature reduces the power dissipation to a mere 15mW and allows multiple amplifiers to drive the same cable. The LT1187 is a low power version of the popular LT1193, and is available in 8-pin miniDIPs and SO packages. For applications with gains of 10 or more, see the LT1189 data sheet. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
