GENERAL DESCRIPTION
The AD7991/AD7995/AD7999 are 12-/10-/8-bit, low power,
successive approximation ADCs with an I2C-compatible interface.
Each part operates from a single 2.7 V to 5.5 V power supply and
features a 1 μs conversion time. The track-and-hold amplifier
allows each part to handle input frequencies of up to 14 MHz,
and a multiplexer allows taking samples from four channels.
Each AD7991/AD7995/AD7999 provides a 2-wire serial
interface compatible with I2C interfaces. The AD7991 and
AD7995 come in two versions and each version has an
individual I2C address. This allows two of the same devices to be
connected to the same I2C bus. Both versions support standard,
fast, and high speed I2C interface modes. The AD7999 comes in
one version.
The AD7991/AD7995/AD7999 normally remain in a shutdown
state, powering up only for conversions. The conversion process
is controlled by a command mode, during which each I2C read
operation initiates a conversion and returns the result over the
I2C bus.
When four channels are used as analog inputs, the reference for
the part is taken from VDD; this allows the widest dynamic input
range to the ADC. Therefore, the analog input range to the
ADC is 0 V to VDD. An external reference, applied through the
VIN3/VREF input, can also be used with this part.
