Thông số kỹ thuật
This is a high-precision single-channel SAR analog-to-digital converter belonging to PulSAR product line from Analog Devices, featuring 18-bit high resolution, low power consumption and zero pipeline delay, designed for precision analog signal sampling and data acquisition systems.
Định nghĩa mã sản phẩm
AD7984 stands for the core model of 18-bit high-speed successive approximation ADC. BRMZ refers to 10-pin MSOP compact surface mount industrial package. RL7 represents standard tape-and-reel reel packaging for automated SMT mass production assembly.
Các thông số hiệu suất điện chính
It adopts pure SAR conversion architecture with full 18-bit resolution and guaranteed no missing codes. The maximum sampling throughput reaches 1.33MSPS. Under full-speed operation, typical power consumption is only 10.5mW, and power consumption can be further reduced under low sampling frequency for battery-powered devices.
Maximum integral nonlinearity is controlled within ±2.25LSB, differential nonlinear error keeps stable, bringing excellent long-term conversion precision. Typical dynamic range hits 99.7dB, with ultra-low noise and harmonic distortion to restore tiny analog input signals accurately.
It supports true fully differential analog input, the input voltage range can be flexibly configured according to external reference voltage ranging from 2.9V to 5V. The chip works on single 2.5V analog power supply, and independent digital IO power pin supports 1.8V, 2.5V, 3V, 5V multiple logic voltage levels, compatible with all mainstream embedded processors and FPGA systems.
Digital communication interface is compatible with SPI, QSPI and DSP standard serial bus. Multiple chips can be cascaded via daisy-chain wiring, and busy status pin is led out to facilitate synchronous sampling control of multi-channel acquisition boards. No pipeline conversion delay exists inside the chip, which is very suitable for multi-channel multiplexing switching acquisition scenarios.
Thông số kỹ thuật về đóng gói và lắp ráp
10-pin narrow body MSOP patch package is adopted, the overall volume is miniaturized and occupies little PCB layout space. It is classified as MSL3 moisture sensitive component, all reflow soldering operations must be finished within 168 hours after unpacking original vacuum packaging. Continuous reel feeding packaging is provided to match fully automatic placement equipment on production lines.
Tiêu chuẩn về môi trường và tuân thủ
Stable working temperature range covers -40℃ ~ +85℃, adapting to industrial workshops, outdoor monitoring equipment and portable testing instruments with drastic temperature changes. The whole component adopts lead-free and halogen-free production process and complies with global environmental material restriction regulations. The compact integrated structure simplifies peripheral signal conditioning circuit design and reduces overall equipment BOM cost.
