157151D-01L

Description

The NI 9260 with Mini XLR, 2-Ch Audio Output Module, part number 157151D-01L, falls under the C Series Analog Output category. This module offers a compact solution designed to meet the requirements for a variety of audio output applications.

It provides 2-channel output, ensuring versatility for dual audio stream output needs. Each channel can deliver an update rate of up to 51.2 k Samples/second, making it suitable for high-fidelity audio applications. The output range of the module is 3 Vrms, combined with a high-resolution 24-bit digital-to-analog converter (DAC), employing a Delta-Sigma architecture for precise and clear audio signal conversion.

The NI 9260 supports connectivity through Mini-XLR (Part Number: 783467-01) and BNC (Part Number: 783466-01) connectors. The output stage for Mini-XLR is described as balanced and fully differential, which is ideal for reducing noise and ensuring high-quality audio signal integrity. For the BNC connectivity, the output stage is pseudo-differential, with the analog output (AO) terminated through a 50 Ohm resistor to ground, optimizing it for a wide range of audio applications.

The module is engineered with robust protection features, including short circuit protection and ±30 V overvoltage protection, safeguarding the module against potential damage from electrical anomalies. The output coupling is DC, which is ideal for applications requiring continuous signal transmission without interruption.

Additionally, the NI 9260 demonstrates impressive accuracy and stability, with a typical gain error of ±0.6%, ±0.05 dB and an offset error of ±0.7%, ±30 mV. Such precision ensures reliable performance in critical audio output tasks. The module’s power consumption is efficiently managed, requiring a maximum of Specification Details Part Number 157151D-01L Category C Series Analog Output Model NI-9260 Description NI 9260 with Mini XLR, 2-Ch Audio Output Module Connectivity Mini-XLR (Part Number: 783467-01), BNC (Part Number: 783466-01) Channels 2-Channel Update Rate 51.2 k Samples/second Output Range 3 Vrms Resolution 24-bit Protection Short circuit protection, ±30 V overvoltage protection Output Stage (Mini-XLR) Balanced and fully differential Output Stage (BNC) Pseudo-differential, AO- terminated through a 50 Ohm resistor to ground Digital-to-Analog Converter 24-bit, Delta-Sigma type Output Coupling DC Gain Error ±0.6%, ±0.05 dB (typical) Offset Error ±0.7%, ±30 mV (typical) Power Consumption 0.93 Watts (maximum)
