The AD1018 is an analog front end (AFE) that has a high precision analog-to-digital converter (ADC), voltage output digital-to-analog converters (VDACs), and current output digital-to-analog converters (IDACs). The ADC signal chain contains four transimpedance amplifier inputs (TIAs), 17 external voltage inputs, nine VDAC monitor channels, 11 IDAC monitor channels, a precharge buffer, and a 1 MSPS successive approximation register (SAR) ADC. The TIAs convert an input current to voltage and use an internal 2.5 V ADC reference for the positive terminal.

These inputs are single-ended. AGNDx is used as the reference signal. An ADC sequencer option is also available to program an automatic channel measurement sequence (see the AD1018 Hardware Reference Manual for more information). The AD1018 provides 11 channels of low noise, low drift IDAC outputs with a full-scale range (0 mA to 20 mA or 0 mA to 50 mA for IDAC0 to IDAC6, and 0 mA to 150 mA or 0 mA to 200 mA for IDAC7 to IDAC10). Each IDAC channel has 16-bit resolution. The AD1018 has nine VDAC channels with 16-bit resolution. Each channel has a voltage output buffer.
