The ADS1015IDGST is a Precision Analogue-to-digital Converter (ADC) with 12 bits of resolution. Designed with precision, power and ease of implementation in mind. It features an onboard reference and oscillator. Data are transferred via an I²C-compatible serial interface, four I²C slave addresses can be selected. It operates from a single power supply ranging from 2.0 to 5.5V. It can perform conversions at rates up to 3300 samples per second (SPS). An onboard PGA is available, that offers input ranges from the supply to as low as ±256mV, allowing both large and small signals to be measured with high resolution. Also features an input multiplexer (MUX) that provides two differential or four single-ended inputs. It operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion and greatly reduces current consumption during idle periods.

• Low current consumption 128SPS to 3.3kSPS Programmable data rate
• Internal low-drift voltage reference
• Internal oscillator
• Internal PGA
• I²C Interface, pin-selectable addresses
• Four single-ended or two differential inputs
• Programmable comparator

The MAX11626EEE+ is a 12bit analogue to digital converter (ADC) with FIFO and internal reference in 16 pin QSOP package. This device has on-chip FIFO, scan mode, internal clock mode, internal averaging and AutoShutdown function. The MAX11626 has four input channels and maximum sampling rate is 300Ksps using an external clock. It includes 10MHz SPI/QSPI/MICROWIRE compatible serial port. This ADC is used in system supervision, data acquisition systems and data logging systems.

The AD5697R, a member of the nanoDAC+™ family, is a low power, dual, 12-bit buffered voltage output digital-to-analog converter (DAC). The device includes a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The AD5697R operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5697R also incorporates a power-on reset circuit and a RSTSEL pin that ensure that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. It contains a per channel power-down feature that reduces the current consumption of the device to 4 µA at 3 V while in power-down mode.

The AD5697R uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz and includes a VLOGIC pin intended for 1.8 V/3 V/5 V logic.
