Spesifikasi
Part Number Definition
AD7799 stands for 24-bit low-power sigma-delta ADC dedicated to precision weak signal acquisition. BRUZ is 16-pin TSOT-23 surface mount package. REEL means tape-and-reel packaging for automated SMT mass production.
Core Electrical Performance Parameters
It is a complete analog front-end ADC integrating multi-channel multiplexer, programmable gain amplifier, internal clock and precision reference voltage, mainly designed for bridge-type sensors, thermal resistance and millivolt-level tiny signal collection. The effective resolution can reach up to 24 bits, with multiple gain options from 1 to 128, which can amplify microvolt weak input signals to the optimal sampling range.
Three single-ended analog input channels are built-in inside the chip, and two channels can be combined into differential input mode to restrain common-mode interference on site. The digital filter can be flexibly configured to realize 50Hz/60Hz power frequency notch filtering, effectively eliminating industrial power grid noise.
Supply voltage range: 2.7V ~ 5.25V. The chip supports multiple power consumption modes. In idle standby state, the current consumption is extremely low, suitable for long-term battery-powered wireless sensor equipment. Communication adopts standard SPI serial interface, which is convenient for MCU to read conversion data and configure register parameters. On-chip 1.17V bandgap reference voltage ensures long-term sampling accuracy without external reference components. It also has power monitoring and overflow alarm functions.
Packaging and Assembly Specifications
16-pin TSOT23 ultra-small surface mount package, compact size greatly reduces PCB occupied area, convenient for miniaturized sensor module design. Moisture sensitivity level MSL3, reflow soldering shall be completed within 168 hours after opening vacuum packaging. Delivered by continuous reel to meet the feeding needs of fully automatic placement machines.
Environmental and Compliance Standards
Industrial operating temperature range: -40℃ ~ +85℃, adaptable to field industrial equipment, outdoor monitoring terminals and portable measuring instruments with large temperature differences. The device adopts lead-free production process and meets RoHS environmental requirements. The highly integrated structure cancels a large number of peripheral conditioning circuits, lowering the difficulty of analog front-end development.
