COMP. BITS 8

BIPOLAR 2

16-bit, 500kHz sampling A/D converter. This device

accurately samples fullscale input signals up to

Nyquist frequencies with no missing codes. The

dynamic performance of the ADS-930 is optimized to

achieve a THD of –89dB and an SNR of 83dB.

functionally complete ADS-930 contains a fast-set-

tling sample-hold ampliﬁ er, a subranging (three-pass)

A/D converter, an internal reference, an on-board FIFO,

timing and control logic, three-state outputs and error-

correction circuitry. Digital inputs/ outputs are TTL.

typically dissipates 3.5 Watts. The unit is offered with

a bipolar input range of ±5V or a unipolar input range

of 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. Typical applications

include radar, sonar, medical/graphic imaging, and

FFT spectrum analysis.
