描述
The LTA604x family true single-supply voltage feedback operational amplifiers feature high speedperformance with 100 MHz of small signal bandwidth and 107 V/μs slew rate. The products arespecified for +3 V, +5 V, and ±5 V supplies, input common mode voltage range extends to 0.2 V below VS− and 1 V from VS+, and output voltage range extends to within 500 mV of either supply rail, allowing wide dynamic range especially desirable in low voltage applications. The LTA604x also offer excellent signal quality of low distortion (-53 dBc with a 2 VPP, 5 MHz output signal) and fast
settling time (66 ns to 0.1%), which make them ideal as buffers to single-supply ADCs. Operating on supplies from +2.5 V to +12.6 V and dual supplies up to ±6.3 V, the LTA604x are ideal for a wide range of applications, from battery-operated systems with large bandwidth requirements
to high speed systems where component density requires lower power dissipation.
The quad LTA6044 device is offeredin SOIC-14L and TSSOP-14L packages.
