5-GHz LMH6401 fully differential digital variable gain amplifier (DVGA) offers the widest bandwidth with DC coupling
and allows signal acquisition of low and high frequencies without the limitation of baluns used in AC-coupled systems.
Having developed a DC coupling
solution on the analog input, it is now possible to acquire more than 2 GHz of instantaneous bandwidth by making use of complex sampling.
3V with an x1 probe, and 300, 30, or 3V with an x10 probe, with AC or DC coupling
Support for IEPE (Integrated Electronic Piezoelectric) inputs, including use of a 4 mA current source with 18 V compliance voltage for AC or DC coupling

Support for IEPE (Integrated Electronic Piezoelectric)inputs, including use of a 2 mA current source and AC or DC coupling
, to interface with an accelerometer and microphone
New features included in both products include a wider output DC coupling
range, optional intelligent power down/power up to allow the chip to enter power savings mode when not in use and output de-emphasis to drive longer traces between chips.
Product features include an auto-sleep mode that delivers 85 percent power consumption savings, wider input amplitude range down to 400 mV, low-power LVDS driver with adjustable output amplitude, cable length indicator to detect the amount of cable at the input and settable output common-mode voltages for DC coupling
to downstream blocks.
6nV/rtHz to minimize distortion -- Provides a high-performance buffer for TI's SAR and delta-sigma ADCs for high-accuracy and low-power systems -- Output common mode control allows for easy DC coupling
, while negative rail input and rail-to-rail output capability simplifies design and shortens development time -- Offers power supply flexibility by accepting single supply of +3 V to +5 V or dual supply of +/-1.
The NI 9234 dynamic signal acquisition module is ideal for vibration and acoustical data logging because engineers can turn on or off IEPE conditioning as well as select AC or DC coupling
- Select whether AC coupling or DC coupling
2 VDC, DC offset correction, power consumption of 500 mW (iT3011) and 625 mW (iT3018), AC and DC coupling
at both input and output, and bias current of 73 mA (iT3011) and 125 mA (iT3018).
