ADS-953
18-Bit, 1MHz, Low-Distortion
Sampling A/D Converters
GENERAL DESCRIPTION
The ADS-953 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 –95dB peak harmonic
distortion (THD), makes the ADS-953 the ideal choice for both
time-domain (medical imaging, scanners, process control) and
frequency-domain (radar, telecommunications, spectrum analy-
sis) applications.
Packaged in a 32-pin, side-brazed, metal-sealed, ceramic TDIP,
the functionally complete ADS-953 contains a fast-settling sam-
ple-hold amplifier, a subranging (two-pass) A/D converter, an
internal reference, timing/control logic, and error-correction cir-
cuitry. Digital input and output levels are TTL, and the ADS-953
only requires the rising edge of the start convert pulse to
operate.
Requiring ±15V and ±5V supplies, the ADS-953 typically dis-
sipates 1.45 Watts. The device is offered with a bipolar (±5V)
analog input range. Models are available for use in either
commercial (0 to +70°C) or extended (–40 to +110°C) operat-
