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.
