BUFFERED REFERENCE VOLTAGE
Many single-supply applications require a mid-supply refer-
ence voltage. The OPA363 and OPA364 offer excellent
capacitive load drive capability, and can be configured to
provide a 0.9V reference voltage, as can be seen in Figure 6.
For appropriate loading considerations, see the
“

section.
AUDIO APPLICATIONS
The OPA363 and OPA364 op amp family has linear offset
voltage over the entire input common-mode range. Com-
bined with low-noise, this feature makes the OPA363 and
OPA364 suitable for audio applications. Single supply 1.8V
operation allows the OPA2363 and OPA2364 to be optimal
candidates for dual stereo-headphone drivers and micro-
phone pre-amplifiers in portable stereo equipment, see Fig-
ures 9 and 10.

DIRECTLY DRIVING THE ADS8324 AND
THE MSP430
The OPA363 and OPA364 series op amps are optimized for
driving medium speed (up to 100kHz) sampling A/D convert-
ers. However, they also offer excellent performance for
higher speed converters. The no crossover input stage of the
OPA363 and OPA364 directly drive A/D converters without
degradation of differential linearity and THD. They provide an
effective means of buffering the A/D converters input capaci-
tance and resulting charge injection while providing signal
gain. Figure 7 and Figure 8 show the OPA363 and OPA364
configured to drive the ADS8324 and the 12-bit
A/D converter on the MSP430.
