FEATURES OF THE APA-AMP INSTRUMENTATION AMPLIFIER
Interactive Microware•s ADA-AMP (tm) instrumentation
amplifier is a versatile signal conditioning accessory. ADA-AMP
facilitates interfacing scientific instruments to IMI's
ADALAB(tm) data acquisition/control interface for the APPLE II
computer. ADA-AMP can amplify voltage input signals as low as
+500 microvolts and can attenuate signals as high as +10 volts.
ADA-AMP's modular design allows you to equip the basic amplifier
with the operational features necessary for your specific
application, including programmable gain/attenuation and 8- to
16-channel differential multiplexers or 16- to 32-channel
single-ended multiplexers. ADA-AMP provides a cost-effective
approach to signal conditioning since it can be upgraded (at the
factory) to include options not specified at the time of initial
purchase. Key specifications and available options for ADA-AMP
are described below.
APA-AHP Specifications
IMI's ADALAB interface card to read full-scale
* Allows
voltages ranging from +500 microvolts to +10 volts.
*
High-quality instrumentation amplifier allows
switch-selectable gains of 0.1, 1, 10 and 100.
amplification is provided by an operational
* Additional
amplifier with variable gain from 1 to 10. Thus, the
overall gain is continuously adjustable from 0.1 to 1000.
*
Differential inputs offer high common mode rejection (70-100
dB) and high input impedance (8 megohms).
*
A low-pass filter smoothes high frequency noise.
time constant is 1 millisecond.
*
Includes 16-pin DIP sockets for input and output1 both
sockets are identical to ADALAB's analog cable.
The normal
terminal connections for D/A, A/D+, A/D- and ground are
* Pin
also provided, similar to IMI's Self-Test Adapter
terminals.
*
Mounted in plastic box 4-1/4" W x 7-1/2 8 L x 3-3/4 8 H.
* Optional programmable attenuation by a factor of 2, 4, 8,
16, 32, 64, 128, 256, 512 or 1024, selected by ADALAB's
digital output bits 4 through 7. This allows your programs
to select high gain for small input voltages and low gain
for large input voltages.
