The National Instruments 776985-01 DAQCard-700 is a multifunction I/O device designed for low-cost, low-power applications in both laboratory and industrial settings. This device is equipped with a Type II PCMCIA slot, making it ideal for reliable remote data acquisition. The DAQCard-700 features 16 single-ended or 8 differential analog input channels, which are software-selectable, and utilizes a 12-bit successive approximation ADC with a maximum sampling rate of 100 kS/s. Users can configure input signal ranges to ±10 V, ±5 V, or ±2.5 V. The device is engineered with a 512-sample FIFO buffer, facilitating data transfer through interrupts or programmed I/O, while ensuring that each input remains within ±9.5 V of AIGND in differential mode, with overvoltage protection of ±30 V regardless of power status.

In addition to analog inputs, the DAQCard-700 provides 8 TTL-compatible digital input and output channels, with a maximum voltage rating of ±5.5 V relating to DGND. The card also includes three counter/timer channels, one of which is dedicated to analog input, featuring 16-bit resolution and an input voltage range of -0.5 V to +5.0 V relative to DGND. Operating from a base clock frequency of 1 MHz with an accuracy of ±0.01%, the card supports a maximum source frequency of 10 MHz, and allows for pulse durations as low as 50 ns.

Power consumption is optimized, drawing 100 mA in operational mode and 70 mA when in power-down mode, using a supply of +5 VDC (±5%). The card is equipped with a 50-pin male I/O connector and complies with installation category I, supporting a maximum working voltage of 30 VAC or 60 VDC. The recommended operating temperature range is 0 to 70 °C, accommodating humidity levels between 5% and 90% RH. The National Instruments 776985-01 DAQCard-700 is a robust solution for diverse data acquisition needs, delivering high performance in compact form factor.
