GENERAL DESCRIPTION
The AD7492, AD7492-4, and AD7492-5 are 12-bit high speed,
low power, successive approximation ADCs. The parts operate
from a single 2.7 V to 5.25 V power supply and feature
throughput rates up to 1.25 MSPS. They contain a low noise,
wide bandwidth track/hold amplifier that can handle
bandwidths up to 10 MHz.
The conversion process and data acquisition are controlled
using standard control inputs allowing for easy interface to
microprocessors or DSPs. The input signal is sampled on the
falling edge of CONVST and conversion is also initiated at this
point. The BUSY pin goes high at the start of conversion and
goes low 880 ns (AD7492/AD7492-4) or 680 ns (AD7492-5)
later to indicate that the conversion is complete. There are no
pipeline delays associated with the part. The conversion result is
accessed via standard CS and RD signals over a high speed
parallel interface.
The AD7492 uses advanced design techniques to achieve very
low power dissipation at high throughput rates. With 5 V
supplies and 1.25 MSPS, the average current consumption
AD7492-5 is typically 2.75 mA. The part also offers flexible
power/throughput rate management.
It is also possible to operate the part in a full sleep mode and a
partial sleep mode, where the part wakes up to do a conversion
and automatically enters a sleep mode at the end of conversion.
The type of sleep mode is hardware selected by the PS/FS pin.
Using these sleep modes allows very low power dissipation
numbers at lower throughput rates.
The analog input range for the part is 0 V to REFIN. The
2.5 V reference is supplied internally and is available for
external referencing. The conversion rate is determined by the
internal clock.
PRODUCT HIGHLIGHTS
1.
High Throughput with Low Power Consumption. The
AD7492-5 offers 1.25 MSPS throughput with 16 mW
power consumption.
2.
Flexible Power/Throughput Rate Management. The
conversion time is determined by an internal clock. The
part also features two sleep modes, partial and full, to
maximize power efficiency at lower throughput rates.
3.
No Pipeline Delay. The part features a standard successive
approximation ADC with accurate control of the sampling
instant via a CONVST input and once-off conversion
control.
4.
Flexible Digital Interface. The VDRIVE feature controls the
voltage levels on the I/O digital pins.
5.
Fewer Peripheral Components. The AD7492 optimizes
PCB space by using an internal reference and internal CLK.
