The AD8040W is an automotive grade version, current of only 1.3 mA per amplifier. Despite their low power qualified for automotive applications. consumption, the amplifiers provide excellent performance with The AD8029/AD8030 are the only low power, rail-to-rail input 125 MHz small signal bandwidth and 60 V/s slew rate. Analog and output high speed amplifiers available in SOT23 and SC70 Devices, Inc., proprietary XFCB process enables high speed and micro packages. The amplifiers are rated over the extended high performance on low power. industrial temperature range, 40C to +125C. This family of amplifiers exhibits true single-supply operation 5.0 INPUT with rail-to-rail input and output performance for supply voltages 4.5 ranging from 2.7 V to 12 V. The input voltage range extends OUTPUT 4.0 200 mV beyond each rail without phase reversal. The dynamic 3.5 range of the output extends to within 40 mV of each rail. 3.0 The AD8029/AD8030/AD8040 provide excellent signal quality 2.5 with minimal power dissipation. At G = +1, SFDR is 72 dBc at 2.0 1 MHz and settling time to 0.1% is only 80 ns. Low distortion and fast settling performance make these amplifiers suitable 1.5 drivers for single-supply analog-to-digital converters. 1.0 G = +1 The versatility of the AD8029/AD8030/AD8040 allows the user V = +5V 0.5 S R = 1k TIED TO MIDSUPPLY 1s/DIV L to operate the amplifiers on a wide range of supplies while con- 0 TIME (s) 03679-A-010 suming less than 6.5 mW of power. These features extend the operation time in applications ranging from battery-powered Figure 5. Rail-to-Rail Response systems with large bandwidth requirements to high speed Rev.
