Analog Devices Inc AD7687BCPZRL7The AD76871 is a 16-bit, charge redistribution, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.3 V to 5.5 V. It contains a low power, high speed, 16-bit sampling ADC with no missing codes, an internal conversion clock, and a versatile serial interface port. The device also contains a low noise, wide bandwidth, short aperture delay track-and-hold circuit. On the CNV rising edge, the AD7687 the samples the voltage difference between IN+ and IN− pins, which can range from −VREFto +VREF. The reference voltage, VREF, is applied externally and can be set up to the supply voltage.The power consumption of the device scales linearly with throughput.The SPI-compatible serial interface also features the ability to daisy-chain several ADCs on a single 3-wire bus and provides an optional BUSY indicator by means of the SDI pin. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic using the separate supply VIO.The AD7687 comes in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +85°C.APPLICATIONSBattery-powered equipmentData acquisitionsInstrumentationMedical instrumentsProcess controls | 10-VFDFN Exposed Pad, CSP | Surface Mount | 10-LFCSP-WD (3x3) | DSP, SPI | S/H-ADC | 2.3 V | 5.5 V | 5.5 V | 2.3 V | Differential | External | -40 °C | 85 °C | 16 bits | SAR | 1 | 1:1 | 1 | 250 k |
