GENERAL DESCRIPTION
The AD7997/AD7998 are 8-channel, 10- and 12-bit, low power,
successive approximation ADCs with an I2C-compatible
interface. The parts operate from a single 2.7 V to 5.5 V power
supply and feature a 2 µs conversion time. The parts contain an
8-channel multiplexer and track-and-hold amplifier that can
handle input frequencies up to 11 MHz.
The AD7997/AD7998 provide a 2-wire serial interface that is
compatible with I2C interfaces. Each part comes in two versions,
AD7997-0/AD7998-0 and AD7997-1/AD7998-1, and each
version allows at least two different I2C addresses. The I2C
interface on the AD7997-0/AD7998-0 supports standard and
fast I2C interface modes. The I2C interface on the AD7997-1/
AD7998-1 supports standard, fast, and high speed I2C interface
modes.
The AD7997/AD7998 normally remain in a shutdown state
while not converting, and power up only for conversions. The
conversion process can be controlled using the CONVST pin,
by a command mode where conversions occur across I2C write
operations or an automatic conversion interval mode selected
through software control.
The AD7997/AD7998 require an external reference that should
be applied to the REFIN pin and can be in the range of 1.2 V to
VDD. This allows the widest dynamic input range to the ADC.

Figure 1.
On-chip limit registers can be programmed with high and
low limits for the conversion result, and an open-drain, out-of-
range indicator output (ALERT) becomes active when the
programmed high or low limits are violated by the conversion
result. This output can be used as an interrupt.
PRODUCT HIGHLIGHTS
1.
2 µs conversion time with low power consumption.
2.
I2C-compatible serial interface with pin-selectable
addresses. Two AD7997/AD7998 versions allow five
AD7997/AD7998 devices to be connected to the same
serial bus.
3.
The parts feature automatic shutdown while not converting
to maximize power efficiency. Current consumption is 1 µA
max when in shutdown mode at 3V.
4.
Reference can be driven up to the power supply.
5.
Out-of-range indicator that can be software disabled or
enabled.
6.
One-shot and automatic conversion rates.
7.
Registers store minimum and maximum conversion
results.
