GENERAL DESCRIPTION

The AD8260 includes a high current driver, usable as a

transmitter, and a low noise digitally programmable variable

gain amplifier (DGA), useable as a receiver.

dynamic range, it is essential that the part be ac-coupled when

operating on a single supply.

The AD8260 preamplifier (PrA) is configured with external

resistors for gains greater than 6 dB and can be inverting or

noninverting. The DGA is characterized with a noninverting

preamplifier gain of 2×. The attenuator has a range of 30 dB and

the output amplifier has a gain of 8× (18.06 dB). The lowest

noninverting gain range is −6 dB to +24 dB and shifts up with

increased preamplifier gain. The gain is controlled via a parallel

port (Pin GNS0 to Pin GNS3) with 10 gain steps of 3 dB per

code. The preamplifier and DGA are disabled for any code that

is not assigned a gain step.

The receiver section consists of a single-ended input preampli-

fier, and linear-in-dB, differential-output DGA. The receiver has

a small signal –3 dB bandwidth of 230 MHz; the driver small

signal bandwidth is 195 MHz. The driver delivers 300 mA,

well suited for driving low impedance loads, even when

connected to a 3.3 V supply.

The AD8260 DGA is ideal for trim applications and has a gain

span of 30 dB, in 3 dB steps. Excellent bandwidth uniformity is

maintained across the entire frequency range. The low output-

referred noise of the DGA is advantageous in driving high

speed ADCs. The differential output facilitates the interface to

modern low voltage high speed ADCs.

The AD8260 can operate with single or dual supplies from 3.3 V

to 5 V. An internal buffer normally provides a split supply

reference for single-supply operation; an external reference

can also be used when the VMID buffer is shut down.

Single-supply and dual-supply operation makes the part versatile

and enables gain control of negative-going pulses, such as those

generated by photodiodes or photo-multiplier tubes, as well as

processing band-pass signals on a single supply. For maximum

The operating temperature range is −40°C to +105°C. The

AD8260 is available in a 5 mm × 5 mm, 32-lead LFCSP.
