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. ADI’s proprietary XFCB process enables high speed and high performance on low power. powered systems with large bandwidth requirements to high speed systems where component density requires lower power dissipation. 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. 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 versatility of the AD8029/AD8030/AD8040 allows the user to operate the amplifiers on a wide range of supplies while consuming less than 6.5 mW of power. These features extend the operation time in applications ranging from battery- INPUT 4.5 4.0 OUTPUT 3.5 VOLTAGE (V) 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 A/D converters. 5.0 3.0 2.5 2.0 1.5 1.0 G = +1 0.5 VS = +5V RL = 1kΩ TIED TO MIDSUPPLY 0 TIME (µs) 1µs/DIV 03679-A-010 Figure 5.
