Footnotes:
All power supplies must be on before applying a start convert pulse. All
supplies and the clock (START CONVERT) must be present during warm-up
periods. The device must be continuously converting during this time. There is
a slight degradation in performance when operating the device in the unipolar
mode.
Effective bits is equal to:
(SNR + Distortion) – 1.76 + 20 log
When COMP. BITS (pin 35) is low, logic loading "0" will be –350μA.
A 1MHz clock with a positive pulse width is used for all production
testing. See Timng Diagramfor more details.
40ns < Start Pulse < 175ns or 280ns < Start Pulse < 460ns
6.02
Full Scale Amplitude
Actual Input Amplitude
This is the time required before the A/D output data is valid once the analog
input is back within the specified range. This time is only guaranteed if the input
does not exceed ±4.75V (bipolar)
or +2 to –7.5V (unipolar).
The mnimumsupply voltages of +4.9V and –4.9V for ±V
DD
are required for
–55°C operation only. The mnimumlimts are +4.75V and –4.75V when
operating at +125°C.
TECHNICAL NOTES
1. Obtaining fully specified performance from the ADS-932
requires careful attention to pc-card layout and power supply
decoupling. The device's analog and digital ground systems
are connected to each other internally. For optimal perfor-
mance, tie all ground pins (4, 7, 30 and 36) directly to a
large
analog
ground plane beneath the package.
Bypass all power supplies and the +3.2V reference output to
ground with 4.7μF tantalum capacitors in parallel with 0.1μF
ceramic capacitors. Locate the bypass capacitors as close
to the unit as possible.
2. The ADS-932 achieves its specified accuracies without the
need for external calibration. If required, the device's small
initial offset and gain errors can be reduced to zero using
the adjustment circuitry shown in Figure 2. When using this
circuitry, or any similar offset and gain calibration hardware,
make adjustments following warm-up. To avoid interaction,
always adjust offset before gain. Tie pins 5 and 6 to
ANALOG GROUND (pin 4) if not using offset and gain adjust
circuits.
3. Pin 35 (COMP. BITS) is used to select the digital output
coding format of the ADS-932 (see Tables 2a and 2b).
When this pin has a TTL logic "0" applied, it complements
all of the ADS-932’s digital outputs.
Pin 35 is TTL compatible and can be directly driven with
digital logic in applications requiring dynamic control over its
function. There is an internal pull-up resistor on pin 35
allowing it to be either connected to +5V or left open when a
logic "1" is required.
4. To enable the three-state outputs, connect OUTPUT
ENABLE (pin 34) to a logic "0" (low). To disable, connect pin
34 to a logic "1" (high).
5. Applying a start convert pulse while a conversion is in
progress (EOC = logic "1") will initiate a new and probably
inaccurate conversion cycle. Data from both the interrupted
and subsequent conversions will be invalid.
