AD605ARZ

The AD605ARZ is one member of the AD605 family which designed as the low noise, accurate, dual channel, linear-in-dB variable gain amplifier that optimized for any application requiring high performance (achieved with the differential input, single-supply, exponential amplifier (DSX-AMP) architecture), wide band-width variable gain control. Also it can be used in ultrasound and sonar time-gain controls, high performance AGC systems and signal measurement.

Features of the AD605ARZ are:(1)low power: 90 mW/channel;(2)drives ADCs directly;(3)single 5 V supply;(4)power shutdown at lower end of gain control;(5)output common mode independently set;(6)single-ended unipolar gain control;(7)stable gain with temperature and supply variations;(8)variable gain scaling: 20 dB/V through 40 dB/V;(9)differential input;(10)bandwidth: 40 MHz (-3 dB);(11)2 independent linear-in-dB channels;(12)input noise at maximum gain: 1.8 nV/Hz, 2.7 pA/Hz.

The absolute maximum ratings of the AD605ARZ can be summarized as:(1)supply voltage +Vs pin 12, pin 13 (with pin 4, pin 5=0 V):6.5 V;(2)input voltage pin 1 to pin 3, pin 6 to pin 9, pin 16:VPOS, 0;(3)internal power dissipation (16-lead PDIP):1.4 W;(4)internal power dissipation (16-lead SOIC_N):1.2 W;(5)operat-ing temperature range:-40°C to +85°C;(6)storage temperature range:-65°C to +150°C;(7)lead temperature, soldering 60 sec:300°C.
