AD7606BSTZ-4

AD7606BSTZ-4 stands for 4-channel simultaneous sampling 16-bit successive approximation analog-to-digital converter. STZ corresponds to 64-lead LQFP surface mount package, delivered in tube packaging for prototype debugging and small-volume industrial equipment assembly.

This multi-channel high-speed ADC features fully integrated analog front-end circuitry without the requirement for external signal conditioning amplifiers or buffer circuits. Four independent input channels conduct synchronous sampling at the same moment, which is essential for phase-consistent acquisition of multi-group analog signals. Each channel is equipped with an onboard programmable input range, supporting ±5 V and ±10 V bipolar input configurations to adapt to mainstream industrial voltage output sensors.

The device achieves a maximum throughput rate of 800 kSPS when all four channels work simultaneously. It incorporates internal digital low-pass filters with adjustable cutoff frequencies to suppress high-frequency interference noise. An integrated high-precision bandgap voltage reference ensures stable conversion accuracy across varying ambient temperatures.

The supply voltage consists of analog 4.75 V to 5.25 V and digital 2.3 V to 5.25 V, allowing flexible matching with different logic level microcontroller systems. Multiple digital output modes including parallel byte interface, serial SPI interface are available for convenient data transmission. Comprehensive internal protection circuits protect input pins against overvoltage damage caused by field wiring errors. Built-in oversampling function can further improve effective resolution and reduce conversion noise for low-frequency measurement scenarios.

Housed in standard 64-pin LQFP plastic surface mount package with regular outline, convenient for PCB layout and automated soldering processes. Moisture Sensitivity Level is MSL3; all reflow soldering processes need to be finished within 168 hours after vacuum packaging is opened. Tube packaging is applied to satisfy manual circuit testing and small batch production demands.

Industrial operating temperature range covers -40 °C to +85 °C, maintaining reliable performance inside power monitoring cabinets, mechanical vibration test platforms, industrial automation controllers and portable data recorders under complex temperature and electromagnetic environments. Produced using lead-free manufacturing technology, the part complies with RoHS international environmental regulations. The all-in-one design greatly reduces the number of peripheral discrete components, lowering the difficulty of multi-channel synchronous acquisition hardware development.
