Figure 59. THD + N Test Circuit
Driving a 16-Bit ADC
The AD865x family is an excellent choice for driving high
speed, high precision ADCs. The driver amplifier for this type
of application needs low THD + N as well as quick settling time.
Figure 61 shows a complete single-supply data acquisition
solution. The AD865x family drives the AD7685, a 250 kSPS,
16-bit data converter.1
The AD865x is configured in an inverting gain of 1 with a 5 V
single supply. Input of 45 kHz is applied, and the ADC samples
at 250 kSPS. The results of this solution are listed in Table 6.
The advantage of this circuit is that the amplifier and ADC can
be powered with the same power supply. For the case of
a noninverting gain of 1, the input common-mode voltage
encompasses both supplies.
