GENERAL DESCRIPTION
The AD7482 is a 12-bit, high speed, low power, successive
approximation ADC. The part features a parallel interface with
throughput rates up to 3 MSPS. The part contains a low noise,
wide bandwidth track-and-hold that can handle input frequencies
in excess of 40 MHz.
The conversion process is a proprietary algorithmic successive
approximation technique that results in no pipeline delays. The
input signal is sampled, and a conversion is initiated on the falling
edge of the CONVST
The part uses advanced design techniques to achieve very low
power dissipation at high throughput rates. Power consumption
in the normal mode of operation is 90 mW. There are two power
saving modes: a nap mode, which keeps the reference circuitry
alive for a quick power-up while consuming 2.5 mW, and a
standby mode that reduces power consumption to a mere 10 μW.
The AD7482 features an on-board 2.5 V reference but can also
accommodate an externally provided 2.5 V reference source.
The nominal analog input range is 0 V to 2.5 V, but an offset
shift capability allows this nominal range to be offset by ±200 mV.
This allows the user considerable flexibility in setting the bottom
end reference point of the signal range, a useful feature when
using single-supply op amps.
The AD7482 also provides an 8% overrange capability via a
13th bit. Therefore, if the analog input range strays outside the
nominal by up to 8%, the user can still accurately resolve the
signal by using the 13th bit.
The AD7482 is powered by a 4.75 V to 5.25 V supply. The part
also provides a VDRIVE pin that allows the user to set the voltage
levels for the digital interface lines. The range for this VDRIVE pin
is 2.7 V to 5.25 V. The part is housed in a 48-lead LQFP package
and is specified over a −40°C to +85°C temperature range.
signal. The conversion process is controlled
via an internally trimmed oscillator. Interfacing is via standard
parallel signal lines, making the part directly compatible with
microcontrollers and DSPs.
The AD7482 provides excellent ac and dc performance specifica-
tions. Factory trimming ensures high dc accuracy, resulting in
very low INL, offset, and gain errors.
