사양
This is a 16-bit 8-channel SAR analog-to-digital converter developed by Analog Devices, integrating multi-channel analog multiplexer, sample hold circuit and precision reference voltage source inside the chip, designed for multi-channel analog signal collection with high precision and low power consumption demands.
부품 번호 정의
LTC1867 represents the core model of 16-bit eight-channel high-speed low-power ADC series. I stands for industrial wide temperature range grade. GN refers to 16-pin narrow-body SSOP surface mount packaging. #PBF means bulk tube packaging delivery for small batch production and prototype debugging.
주요 전기적 성능 매개변수
It adopts full 16-bit conversion resolution without missing codes in the whole working range, maximum integral nonlinear error is controlled within ±2LSB. The maximum sampling rate reaches 200ksps, built-in clock circuit trimmed by factory calibration ensures stable conversion speed under temperature variation.
Equipped with 8-way analog input channel, users can flexibly configure working mode as single-ended input or differential input, and switch unipolar/bipolar voltage conversion arbitrarily to adapt to various sensor output signals.
Single 5V power supply design, quiescent current is only 1.3mA under full-speed sampling state; automatic dormant mode will be activated between conversion cycles to cut down power consumption greatly, and ultra-low current sleep mode is reserved for long standby battery-powered equipment.
On-chip integrated 2.5V temperature-compensated bandgap reference source, users can choose internal reference or access external high-precision reference voltage according to accuracy requirements. Digital communication interface complies with SPI and MICROWIRE standards, convenient to connect with MCU and FPGA for data reading. Typical signal-to-noise ratio reaches 89dB, with excellent noise suppression capability to capture tiny analog voltage changes accurately.
포장 및 조립 사양
16-pin narrow SSOP patch packaging is adopted, the overall size is compact, occupying less PCB layout space. It belongs to MSL3 moisture sensitive component, all reflow soldering procedures must be finished within 168 hours after opening original vacuum packaging. Tube bulk packaging is adopted, suitable for laboratory circuit development, equipment trial production and small batch assembly.
환경 및 규정 준수 기준
Continuous stable operating temperature range covers -40℃ ~ +85℃, adapting to industrial cabinet equipment, outdoor monitoring terminals and portable testing instruments with drastic ambient temperature fluctuation. The product is manufactured with lead-free process and complies with global environmental material control regulations. Highly integrated structure removes lots of peripheral matching circuits, simplifies multi-channel data acquisition hardware design effectively.
