SOIC-14 (R) and TSSOP-14 (RU) GENERAL DESCRIPTION The AD8029 (single), AD8030 (dual), and AD8040 (quad) are rail-to-rail input and output high speed amplifiers with a quiescent current of only 1.3 mA per amplifier. Despite their low power consumption, the amplifiers provide excellent performance with 125 MHz small signal bandwidth and 60 V/µs slew rate. Analog Devices, Inc., proprietary XFCB process enables high speed and high performance on low power. This family of amplifiers exhibits true single-supply operation with rail-to-rail input and output performance for supply voltages ranging from 2.7 V to 12 V. The input voltage range extends 200 mV beyond each rail without phase reversal. The dynamic range of the output extends to within 40 mV of each rail. The AD8029/AD8030/AD8040 provide excellent signal quality with minimal power dissipation. At G = +1, SFDR is –72 dBc at 1 MHz and settling time to 0.1% is only 80 ns. Low distortion and fast settling performance make these amplifiers suitable drivers for single-supply analog-to-digital converters. The versatility of the AD8029/AD8030/AD8040 allows the user to operate the amplifiers on a wide range of supplies while con- suming less than 6.5 mW of power. These features extend the operation time in applications ranging from battery-powered systems with large bandwidth requirements to high speed systems where component density requires lower power dissipation. The AD8040W is an automotive grade version, qualified for automotive applications. The AD8029/AD8030 are the only low power, rail-to-rail input and output high speed amplifiers available in SOT23 and SC70 micro packages. The amplifiers are rated over the extended industrial temperature range, –40°C to +125°C.
