Introduction
The ADC5020/ADC5030 18-bit A/D converter, designed with a unique
sub-ranging architecture, achieves excellent speed, accuracy, and lineari-
ty. For digitizing fast time-varying signals, the ADC5020 has a built-in sam-
ple-and-hold amplifier. For applications with multiplexed DC signals or an
external sample-and-hold, the more economical ADC5030 is available
with a high impedance input buffer in place of the sample-and-hold. With a
144 kHz sampling rate, the ADC5020 can digitize professional audio sig-
nals (20 Hz to 20 kHz) at 3X oversampling, minimizing the design com-
plexity of the anti-aliasing filters. The high sampling rate, low noise, low
distortion and superior zero-crossing linearity of the ADC5020 optimize
this converter for professional audio and spectroscopic applications.
The ADC5020/ADC5030’s sub-ranging architecture uses a three-pass
recycling technique in a design that both minimizes parts count and
yields unprecedented stability, linearity, and accuracy. To achieve this su-
perior performance, the ADC5020/ADC5030 relies on a proprietary refer-
ence D/A converter that has inherent 18-bit accuracy and linearity. The
D/A converter, in conjunction with logic circuitry in a specialized gate
array, detects and corrects inaccuracies and linearity errors that could
arise from the flash A/D converter and amplifier circuitry in the conversion
path. For applications requiring fine offset and gain adjustments, the con-
verter has provisions for dynamically setting these DC parameters. The
ADC5020/ADC5030 also provides easily accessible offset-trim and gain-
trim potentiometers. This truly unique product comes in a fully-shielded 3"
x 4" module with 0.1" pin spacings for easy installation on printed circuit
boards. The specifications of the ADC5020/ADC5030 are fully ensured
by thorough, computer-controlled factory tests.
