AD7683 is a 16-bit 100kSPS Pulsar ADC manufactured by Analog Devices. It supports MSOP and QFN packages. Its features include 16-bit resolution with no missing codes, 100kSPS throughput, ±1LSB typical integral nonlinearity, 0V to VREF analog input range, VREF up to VDD, single-supply operation 2.7V to 5.5V, SPI®/QSPI™/MICROWIRE™/DSP compatible interface, power dissipation 4mW@5V, [email protected], 150µ[email protected]/10kSPS, standby current 1nA. Applications include battery-powered equipment, data acquisition, instrumentation, medical instruments, process control.
The AD7683 is a 16‑bit, charge‑redistribution successive‑approximation ADC that operates from a single 2.7 V to 5.5 V supply. It offers 100 kSPS throughput, low power consumption (4 mW @5 V) and a standby current of 1 nA. The device is supplied in an 8‑lead MSOP or 8‑lead QFN (LFCSP) package and is rated for –40 °C to +85 °C operation.
Key features include a serial SPI‑compatible interface, no missing codes, low noise, and a wide input range (0 V to VDD). The datasheet provides detailed specifications, timing diagrams, pin descriptions, and absolute maximum ratings for designers.
