National Instruments 779676-01 Multifunction I/O Device
The part number 779676-01 from National Instruments is the identifying part number for the USB-6211 Multifunction I/O Device. This multifunction I/O device features 8 differential or 16 single-ended analog input channels with an analog-to-digital (ADC) 16-bit resolution. Its maximum single-channel and multichannel sampling rate is 250 kS per second with no minimum sample rate. It offers various input voltage ranges of ±0.2 V, ±1 V, ±5 V, and ±10 V with an input coupling of DC.
Its input impedance is less than 10 GΩ in parallel with 100 pF when the device is ON while 1,200 Ω when the device is OFF and has an input bias current of ±100 pA. Thus, these features, ensure high accuracy and minimal interference in signal measurement applications. The high impedance when powered on and low bias current make it suitable for precision measurements, while the lower impedance when off necessitates careful handling to maintain signal integrity
The 779676-01 device has 2 analog output channels with a digital-to-analog converter (DAC) 16-bit resolution and has a maximum update rate of 250 kS per second on 1 channel and 2 channels. Its output voltage range is ±10 V and an output coupling of DC. Its output impedance is very low at 0.2 Ω and has an output current drive of ±2 mA with an overdrive protection rating of ±30 V. It also offers a FIFO buffer memory size of 8,191 samples for each channel used and a data transfer method of USB Signal Stream, and programmed I/O.
To operate this multifunction I/O device, its power requirements are 400 mA at 4.5 V with a suspended maximum current load of 260 μA typically. Its maximum inrush current rating is 500 mA and no load typical current of 320 mA at 4.5 V. Physically, this module has a firm structure with dimensions of 16.9 cm × 9.4 cm × 3.1 cm (6.65 in. × 3.70 in. × 1.20 in.) and weighs 206 g (7.2 oz). It is also equipped with a 2 16-position combicon I/O connector that allows easy integration into digital devices.
