75MHZ RAIL-TO-RAIL OP-AMPS FROM NATIONAL SEMICONDUCTOR BRING HIGH SPEED TO 2.7V PORTABLE SYSTEMS

Wide Gain-Bandwidth: 10MHz & 75MHz

Low Supply Current Maximizes Battery Life

Rail-to-Rail Input and Output

Wide Operating Voltage Range: 2.7V to 24V

Nov 29, 1995

SANTA CLARA, CA., November 29, 1995 - A series of rail-to-rail input and output operational amplifiers which offer high-speed operation at low supply currents has now been introduced by National Semiconductor. Each of these amplifiers addresses the needs of the portable instrumentation market by providing excellent signal fidelity through its wide bandwidth, and by offering a broad supply range of 2.7V to 24V, easing overall design in mixed-voltage applications.

The LM6132 (dual) and the LM6134 (quad), each operate at a fast 10MHz while drawing only 360microA/Channel (typ.) of supply current. While the rail-to-rail input and output of these amplifiers increase overall performance by maximizing signal-to-noise ratio and dynamic signal range, the low supply current minimizes battery consumption, prolonging battery life. This combination of features makes these devices ideal for use in high-speed portable instrumentation such as barcode scanners, LCDs and other battery-powered devices.

"This amplifier provides designers with the low-power operation needed for portable devices, but, unlike many products on the market today, does not compromise speed to do so," noted Sonia Ramirez, National's amplifier product marketing engineer. "Also, this combination of rail-to-rail input and output, high speed operation, and minimal power consumption is offered at a price that won't inflate the overall system cost."

For those applications which demand even greater bandwidth, the LM6152 (dual) and the LM6154 (quad) offer rail-to-rail operation at a speed as high as 75MHz. With the same variable supply range of 2.7V to 24V, these amplifiers offer a high-speed solution for low voltage applications. This combination of features makes the LM6152/4 ideal for high- speed portable instrumentation and data converter signal conditioning applications.
