Supply Current: 1.6mA These devices were specifically designed to drive typical headset Single-Supply Operation: 2.7V to 5.5V levels (32), as well as bias RF power amplifiers for wireless handset applications. Gain-Bandwidth Product: 10MHz The devices are available as the standard products shown in High Slew Rate: 10V/s Table 1. See also Ordering Information on page 18. Voltage Gain: 100dB (RLOAD = 100k ) Table 1. Standard Products Power-Supply Rejection Ratio: -85dB Model Description Package No Phase Reversal for Overdriven Inputs AS1710A Single Op Amp with Shutdown SC70-6 Unity-Gain Stable for Capacitive Loads: Up to 100pF AS1710B Single Op Amp SC70-5 AS1712A Quad Op Amp with Shutdown TQFN-16 Shutdown Mode (AS1710A) Current: 1nA typ (3x3mm) Package Types: - SC70-6 These rail-to-rail I/O, wide-bandwidth amplifiers exhibit a high slew - SC70-5 rate of 10V/s and a gain-bandwidth product of 10MHz. -TQFN-16 (3x3mm) The integrated shutdown feature (not included in B versions) drives the output low. 3 Applications These devices operate over the entire industrial temperature range (-40C to +85C). The devices are ideal for portable/battery-powered audio applications, portable headphone speaker drivers (32 ), hands-free mobile phone kits, TFT panels, sound ports/cards, set-top boxes, biasing controls, DAC converter buffers, transformer/line drivers, motor drivers, and any other battery-operated audio device.
