DESCRIPTION
The VSP1000 is a high-speed, low-noise, low-power,
fast-settling, unity-gain buffer. It is specially designed
for use between charge-coupled device (CCD)
sensors and analog front-ends (AFEs). The device
has an adjustable active load current that can load
the CCD sensor output appropriately. The VSP1000 also features an adjustable output drive strength that
can be set in accordance with the bandwidth
requirements. At a 2-mA drive current, the device
provides a bandwidth of 210 MHz, which allows for
very low power operation with good performance. An
ultra-small package of 1 mm × 1 mm and 0.35-mm
height helps in saving printed circuit board (PCB)
space and achieving a very low profile.
The VSP1000 is ideal for driving Texas Instruments
AFEs for CCD sensors and, in general, any
analog-to-digital converter (ADC) inputs. The
adjustable load current allows for easy interfacing
with a variety of CCD sensors from various
manufacturers.
