BLOCK DIAGRAM
The ADS-919 is a high-performance, 14-bit,
2MHz sampling A/D converter. This device
accurately samples full-scale input signals up to
Nyquist frequencies with no missing codes. The
ADS-919 features outstanding dynamic perfor-
mance including a THD of –74dB.
Housed in a small 24-pin DDIP or SMT (gull-
wing) package, the functionally complete ADS-919
contains a fast-settling sample-hold amplifier, a sub-
ranging (two-pass) A/D converter, a precise voltage
reference, timing/control logic, and error correction
circuitry. Digital input and output levels are TTL.
Requiring ±15V (or ±12V) and +5V supplies,
the ADS-919 typically dissipates 1.8W (1.5W
for ±12V). The unit is offered with a unipolar
input (0 to +10V). Models are available for use in
either commercial (0 to +70°C) or HI-REL (–55 to
+125°C) operating temperature ranges. Applica-
tions include radar, sonar, spectrum analysis, and
graphic/medical imaging.
