Dual Epad® Precision High Slew Rate Cmos Operational Amplifier

Sunnyvale, CA., -- November 1, 2002 Advanced Linear Devices, Inc., announces a new, high slew-rate Dual Precision CMOS Operational amplifier. Designated the ALD2724E/ALD2724, this device is a high precision version of the ALD1704 Operational Amplifier, which is designed to offer an alternative to the popular JFET input operational amplifiers with improved specifications and added features. The ALD2724E permits optional user-programmable offset voltage trimming using the patented "EPAD®" (Electrically Programmable Analog Device) technology. The ALD2724, which is pre-programmed at the factory under standard operating conditions for minimum Vos, is intended for standard operational amplifier applications where little or no electrical programming by the user is necessary. These op-amps are ideally suited for applications in portable instruments, sensor pre-amplifiers, transducer biasing, and precision gain circuits where mechanical potentiometer trimming is not a viable alternative.

Standard offset voltage specifications for the ALD2724E/ALD2724 are typically 25mV at 0.01pA input bias current. The ALD2724E has a guaranteed input offset programming range of +/- 5 mV and is recommended for applications requiring electrical user-programming for further Vos trimming using an ALD E100 EPAD Programming Unit and Adapter Module.

Both devices feature rail-to-rail input and output voltage ranges, tolerance to over-voltage input of 300mV beyond supply rails, +/- 5V supply operation, high capacitive loading up to 4000pF, extremely low input currents of 0.01pA typical, high open loop voltage gain, 2.1MHz bandwidth, slew rate of 5 V/ms, and supply current of 5.0mA. Also featured is fully static internal circuitry and DC operating device architecture, with no internal running clock that may occasionally cause cross-talk interference.

The ALD2724E/ALD2724 is priced at $1.83/ $1.46 respectively in 1k piece quantities with delivery available from stock. These devices are available in 14 pin PDIP, SOIC, and ceramic DIP packages. These devices are also available as standard cells for mixed Analog/Digital ASIC Arrays. For more information, contact marketing at (408) 747-1155 or visit our web site at
