ADI AD1030BCBZ-RL7

The AD1030 is an analog front end (AFE) that includes a high precision analog-to-digital converter (ADC), voltage output digital-to-analog converters (VDACs), current output digital-to-analog converters (IDACs), thermoelectric cooler (TEC) controller, and analog comparators. The ADC signal chain contains two analog comparator channels, 10 external voltage inputs, VDAC voltage and current monitor channels, IDAC voltage and current monitor channels, a precharge buffer, and a 1 MSPS successive approximation register (SAR) ADC. The AD1030 provides four IDAC channels. These are low noise, low drift current sources with programmable full-scale output ranges 50mA, 100mA or 150mA. Each IDAC channel has 12-bit resolution. There are 9x 12-bit VDAC outputs. Four of these VDACs (Channel 0 to Channel 3) support either a positive voltage range of 0V to 2.5V or a negative range from 0V to -2.5V. These ranges can be extended to 0V to AVDD and 0V to AVDDNEG. Channel 4 to Channel 7 of the VDACs support a positive voltage range of 0V to 2.5V. VDAC Channel 8 supports a positive voltage range of 0V to 2.5V. Optionally, Channel 4 to Channel 7 of the VDACs can support an output range of 0V to AVDD. The AD1030 also integrates a TEC controller with a heating and cooling current up to 1.3A, is over 90% efficient, and supports a soft start function. Use the 4-wire serial port interface (SPI) for up to 40 MHz or the 2-wire 12C interface for up 1 MHz to configure each functional block and to collect the ADC data.
