Specifications
All specifications are subject to change without notice.
Typical for 25 °C unless otherwise specified.
These specifications apply to both standard and OEM versions unless otherwise
specified.
Analog Input
A/D converter type: Successive approximation
ADC resolution: 16 bits
Number of channels : 4 differential, 8 single-ended (software-selectable)
Input voltage range: ±10 V, ±5 V, ±2 V, ±1 V (software-selectable per channel)
Absolute max input voltage (CHx relative to AGND): ±20 V max (power on),
±12 V max (power off)
Input impedance: 1 GΩ (power on), 1200 Ω (power off)
Input bias current: ±10 nA
Input bandwidth (all input ranges, small signal (–3 dB)): 700 kHz
Input capacitance: 60 pf
Max working voltage (signal + common mode)
±10 V range: ±10.2 V max relative to AGND
±5 V range: ±10.2 V max relative to AGND
±2 V range: ±9.5 V max relative to AGND
±1 V range: ±9.0 V max relative to AGND
Common mode rejection ratio (f
IN
= 60 Hz, all input ranges): 86 dB
Crosstalk (adjacent differential mode channels, DC to 10 kHz): –75 dB
Input coupling: DC
Sample rate: 0.019 Hz to 250 kHz, software-selectable
Trigger source: TRIG (see External Trigger)
Sample clock source: Internal A/D clock or external A/D clock (AICKI pin)
Internal sample clock stability: ±50 ppm
Internal sample clock timebase: 80 MHz timer with 32-bit period (available
frequencies are 80 MHz / integer period)
Throughput
This is the typical throughput when the device and host are both connected by
Ethernet to the same local network. The throughput can vary significantly if a wire-
less connection is involved or data is sent over the internet and is not guaranteed
Software paced: 1000 S/s to 5000 S/s typ, on local network
Hardware paced: 250 kS/s max
Channel gain queue (up to 8 elements): Software-selectable channel and range
for each queue element
Warm-up time: 15 minutes min
