The AD5590 is a 16-channel input and 16-channel output analog I/O port with eight uncommitted amplifiers, operating from a single 4.5 V to 5.25 V supply. The AD5590 comprises 16 input channels multiplexed into a 1 MSPS, 12-bit successive approximation ADC with a sequencer to allow a preprogrammed selection of channels to be converted sequentially. The ADC contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 1 MHz.The conversion process and data acquisition are controlled using ASYNC and the serial clock signal, allowing the device to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of ASYNC and conversion is also initiated at this point. There are no pipeline delays associated with the ADC. By setting the relevant bits in the control register, the analog input range for the ADC can be selected to be a 0 V to VREFA input or a 0 V to 2 ? VREFA with either straight binary or twos complement output coding. The conversion time is determined by the ASCLK frequency because it is also used as the master clock to control the conversion.The DAC section of the AD5590 comprises sixteen 12-bit DACs divided into two groups of eight. Each group has an on-chip reference. The on-board references are off at power-up, allowing the use of external references. The internal references are enabled via a software write.The AD5590 incorporates a power-on reset circuit that ensures that the DAC outputs power up to 0 V and remain powered up at this level until a valid write takes place. The DAC contains a power-down feature that reduces the current consumption of the device and provides software-selectable output loads while in power-down mode for any or all DAC channels. The outputs of all DACs can be updated simultaneously using the LDAC function, with the added functionality of user-selectable DAC channels to simultaneously update. There is also an asynchronous CLR that updates all DACs to a user-programmable code: zero scale, midscale, or full scale.The AD5590 contains eight low noise, single-supply amplifiers. These amplifiers can be used for signal conditioning for the ADCs, DACs, or other independent circuitry, if required.APPLICATIONS Optical Line Cards (Monitoring and Control) Base Stations General Purpose Analog I/O Monitoring and control

The AD5593R has eight input/output (I/O) pins, which can beindependently configured as digital-to-analog converter (DAC)outputs, analog-to-digital converter (ADC) inputs, digital outputs,or digital inputs. When an I/O pin is configured as an analogoutput, it is driven by a 12-bit DAC. The output range of theDAC is 0 V to VREF or 0 V to 2 ? VREF.

Thestate of the GPIO pins can be set or read back by accessing theGPIO write data register and GPIO read configuration registers,respectively, via an I2C write or read operation.The AD5593R has an integrated 2.5 V, 20 ppm/?C reference thatis turned off by default and an integrated temperature indicatorthat gives an indication of the die temperature.
