Combining OUT A 1 14 OUT D high input impedance, low input bias current, wide bandwidth, IN A 2 13 IN D fast slew rate, and fast settling time, the ADA4000-1/ADA4000- +IN A 3 12 +IN D ADA4000-4 2/ADA4000-4 are ideal amplifiers for driving analog-to-digital +V 4 11 V TOP VIEW inputs and buffering digital-to-analog converter outputs. The (Not to Scale) +IN B 5 10 +IN C input common-mode voltage includes the positive power supply, IN B 6 9 IN C OUT B 7 8 OUT C which makes the device an excellent choice for high-side signal conditioning. Figure 5. 14-Lead SOIC (R-14) Additional applications for the ADA4000-1/ADA4000-2/ OUT A 1 14 OUT D ADA4000-4 include electronic instruments, automated test 2 IN A 13 IN D equipment (ATE) amplification, buffering, integrator circuits, 3 +IN A 12 +IN D ADA4000-4 instrumentation-quality photodiode amplification, and fast TOP VIEW 4 11 +V V precision filters (including phase-locked loop filters). The devices (Not to Scale) 5 10 +IN B +IN C also include utility functions, such as reference buffering, level 6 9 IN B IN C shifting, control input/output interface, power supply control, 7 8 OUT B OUT C and monitoring functions.
