AD7693BRMZ

AD7693 is a 16-bit charge-redistribution successive approximation register analog-to-digital converter. BRMZ represents 10-lead tiny MSOP surface mount package, delivered in tube packaging for prototype verification and small batch assembly.

It is a low-power, high-speed single-channel SAR ADC with 16-bit no-missing-code resolution. The device works under single 2.7 V to 5.5 V power supply, supporting two unipolar input voltage ranges: 0 V to 2.5 V and 0 V to 5 V. It features an internal integrated 2.5 V precision bandgap reference voltage source, which can be enabled or disabled on demand to save power consumption.

The maximum throughput rate reaches 500 kSPS. A serial SPI compatible digital interface is adopted for data transmission and register configuration, which can be easily connected to mainstream microcontrollers and FPGAs. The power consumption varies dynamically with sampling speed: only 1.5 mW under full-speed operation, while less than 1 μA in deep power-down mode, perfectly fitting battery-powered portable measuring devices and wireless sensor nodes.

The input stage is equipped with inherent high input impedance, eliminating the need for buffer amplifiers in most conventional signal acquisition scenarios. Ultra-low total harmonic distortion and noise performance ensure accurate conversion of tiny analog voltage signals. No complicated peripheral compensation circuits are required for basic conversion functions.

Encapsulated in compact 10-pin MSOP small outline surface mount package, the miniature footprint effectively saves PCB layout space for miniaturized circuit modules. Moisture Sensitivity Level is MSL3; all reflow soldering procedures must be completed within 168 hours once the vacuum package is opened. Tube packaging is provided to meet the needs of manual debugging and small-scale trial production.

The industrial operating temperature range is from -40 °C to +85 °C, enabling stable operation in industrial field monitoring terminals, handheld testing instruments and outdoor environmental collection equipment under fluctuating temperature conditions. Manufactured with lead-free materials, the component conforms to global RoHS environmental standards. The streamlined peripheral circuit design shortens the development cycle of analog front-end acquisition hardware.
