The devices also include utility functions, such as reference buffering, level shifting, control input/output interface, power supply control, and monitoring functions. –V 4 ADA4000-2 OUT B TOP VIEW (Not to Scale) 6 –IN B 5 +IN B Figure 4. 8-Lead MSOP (RM-8) OUT A 1 14 OUT D –IN A 2 13 –IN D ADA4000-4 12 +IN D TOP VIEW (Not to Scale) 11 –V 10 +IN C –IN B 6 9 –IN C OUT B 7 8 OUT C +IN A 3 +V 4 +IN B 5 05791-029 The ADA4000-1/ADA4000-2/ADA4000-4 are junction field effect transistor (JFET) input operational amplifiers featuring precision, very low bias current, and low power. Combining high input impedance, low input bias current, wide bandwidth, fast slew rate, and fast settling time, the ADA4000-1/ADA40002/ADA4000-4 are ideal amplifiers for driving analog-to-digital inputs and buffering digital-to-analog converter outputs. The input common-mode voltage includes the positive power supply, which makes the device an excellent choice for high-side signal conditioning. +V 7 Figure 5. 14-Lead SOIC (R-14) 14 OUT D OUT A 1 –IN A 2 +IN A 3 +V 4 +IN B 5 13 –IN D ADA4000-4 TOP VIEW (Not to Scale) 12 +IN D 11 –V 10 +IN C –IN B 6 9 –IN C 7 8 OUT C OUT B 05791-030 GENERAL DESCRIPTION 8 05791-028 OUT A 1 Figure 6. 14-Lead TSSOP (RU-14) Rev.
