4-channel, 12-/10-/8-bit Adc With I2ccompatible Interface In 8-lead Sot23

The AD7991 AD7995 AD7999 are 12-/10-/8-bit, low power, successive approximation ADCs with an I 2 C-compatible Interface The parts operate from a single 2.7 V to 5.5 V power supply and feature a 2 s conversion time. The part contains a 4-channel multiplexer and track-and-hold Amplifier that CAN handle input frequencies up to 11 MHz. The AD7991 AD7995 AD7999 provides a 2-wire serial Interface compatible with I 2 C Interfaces The parts come in two versions with each part having an individual I 2 C address. This will allow two of the same devices be connected to the same I 2 C bus. Both parts support standard, fast and high-speed I 2 C Interface modes The AD7991 AD7995 AD7999 normally remain in a shutdown state while not converting, and power up only for conversions. The conversion process is controlled by a command mode, where every time an I 2 C read operation is executed on the AD7991 AD7995 AD7999 a conversion is performed and the result is returned on the I 2 C bus. The reference for the part is taken from VDD, this allows the widest dynamic input range to the ADC Thus the Analog input range to the ADC is 0V to VDD. An external reference may also be used with this part. The external reference may be applied through the Ain3 input. By Analog Devices, Inc.
