... This op amp is also useful in multichannel, high speed data conversion where its fast ( 0.1%) settling time is important. In such applications, the AD829 serves as an input buffer for 8-bit to 10-bit ADCs and as an output I/V converter for high speed DACs. Rev. I Information furnished by Analog Devices is believed to be accurate and reliable ...

... T Figure 35, the AD829 input stage consists of an NPN differential pair in which each transistor operates at a 600 µA collector current. This gives the input devices a high transconductance, which in turn gives the AD829 a low noise figure of 2 nV/√ kHz. 12.5pF +IN –IN 1.2mA ...

... V/µs, which is barely enough to provide a full power bandwidth of 50 kHz. The AD829 is especially suited to a form of current feedback compensation that allows for the enhancement of both the full power bandwidth and the slew rate of the amplifier. The voltage gain from the inverting input pin to the compensation pin is large ...

... MHz. For example, with and R COMP small signal bandwidth of the AD829 is 10 MHz. Figure 40 shows that the slew rate is in excess of 60 V/µs. As shown in Figure 41, the closed-loop bandwidth is constant for gains of −1 to −4; this is a property of the current feedback amplifiers. ...
