GENERAL DESCRIPTION
The AD9005B is a complete 12-bit A/D converter that includes
on-board track-and-hold amplifier, voltage reference, and tim-
ing circuits. Featuring sampling rates from dc to 10 MSPS, the
AD9005B uses a subranging converter architecture to achieve
high speed and high resolution. Dynamic performance includes
an SNR of 64 dB and harmonic distortion of –72 dBc with a
4.3 MHz analog input.
This unit replaces its predecessor, the AD9005A. The AD9005B
uses a higher level of integration than the earlier design to pro-
vide increased performance, better reliability and reduced cost.
The AD9005B requires only +5 V and –5.2 V supplies (elimi-
nating the +15 V and –15 V requirements of the AD9005A).
The AD9005B will operate without board modification in
AD9005A sockets because +15 V and –15 V pins are not
internally connected. All grades are fully tested for dynamic
performance.
Critical to the performance of the AD9005B is the use of ad-
vanced bipolar integrated circuits, custom designed for this
device and manufactured by Analog Devices. The AD9005B is
TTL-compatible with offset binary outputs. It is available in a
46-lead hermetic metal DIP in two temperature ranges: 0
°
C to
+70
°
C commercial range and –55
°
C to +125
°
C military range
(case temperature).
