1 / 17 page  AS1710/AS1712 High-Output-Drive, 10MHz, 10V/µs, Rail-to-Rail I/O Op Amps with Shutdown Dat a Sh eet www.austriamicrosystems.com Revision 1.04 1 - 17 1 General Description The AS1710/AS1712 are low-offset, high-output CMOS op amps that deliver 200mA of peak output current from a single supply (2.7 to 5.5V). These devices were specifically designed to drive typical headset levels (32 Ω), as well as bias RF power amplifi- ers for wireless handset applications. The devices are available as the standard products shown in Table 1. See also Ordering Information on page 16. These rail-to-rail I/O, wide-bandwidth amplifiers exhibit a high slew rate of 10V/µs and a gain-bandwidth product of 10MHz. The integrated shutdown feature (not included in B ver- sions) drives the output low. These devices operate over the entire automotive tem- perature range (-40°C to +125°C). Figure 1. Typical Application 2 Key Features ! Constant Output Drive Capability: 50mA ! Rail-to-Rail Input and Output ! Supply Current: 1.6mA ! Single-Supply Operation: 2.7 to 5.5V ! Gain-Bandwidth Product: 10MHz ! High Slew Rate: 10V/µs ! Voltage Gain: 100dB (RLOAD = 100k Ω) ! Power-Supply Rejection Ratio: -85dB ! No Phase Reversal for Overdriven Inputs !
