BLOCK DIAGRAM
The ADS-951 is an 18-bit, 1MHz sampling
A/D converter. This device accurately samples
full-scale input signals up to Nyquist frequencies
with no missing codes. This feature, combined
with excellent signal-to-noise ratio (SNR) and total
harmonic distortion (THD), makes the ADS-951 the
ideal choice for both time-domain (medical imag-
ing, scanners, process control) and frequency-
domain (radar, telecommunications, spectrum
analysis) applications.
Packaged in a 32-pin, metal-sealed, ceramic
TDIP, the functionally complete ADS-951 contains
a fast-settling sample-hold amplifier, a subranging
(two-pass) A/D converter, an internal reference,
timing/control logic, and error-correction circuitry.
Digital input and output levels are TTL, and the
ADS-951 only requires the rising edge of the start
convert pulse to operate.
Requiring ±15V and ±5V supplies, the ADS-
951 typically dissipates 1.45 Watts. The device is
offered with a bipolar (±5V) analog input range.
Models are available for use in either commer-
cial (0 to +70°C) or extended (–40 to +110°C)
operating temperature ranges. A proprietary,
auto-calibrating, error-correcting circuit enables
the device to achieve specified performance over
the full HI-REL temperature range.
