Featuring high slew rates and low power, two ICs from Linear Technology are designed for battery-powered systems and data-acquisition applications in filter, buffer, and preamp functions. The dual-amplifier LT1352 and quad-amplifier LT1353 slew at 200V/µsec with 3-MHz gain-bandwidth product; current consumption is 250 µA/channel. Each amplifier can drive a 1-k Ohm load to ±13V from ±15V supplies or a 500 Ohm load to ±3.4V using ±5V supplies. The amplifiers are stable with capacitive loads as high as 10,000 pF.
Although these op amps are fast, they also provide dc precision. Maximum input-offset voltage is 600 µV, maximum input-bias current is 50 nA, and maximum input-current offset is 15 nA. Minimum dc gain with a 2-k Ohm load is 30V/mV. The dual LT1352 is available in eight-lead DIP and SOIC packages and costs $4.10 (1000); the quad LT1353 is available in a 14-lead SO package and costs $6.70 (1000).
