The AD7899SRZ-1 is a 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices, optimized for single-supply operation and delivered in a 28-lead SOIC package. It integrates a track-and-hold amplifier, an on-chip reference, and a high-speed parallel interface that directly connects to microprocessors and DSPs. The converter achieves a maximum throughput rate of 400 kSPS while maintaining low power dissipation, and it accepts bipolar analog input signals. The combined signal chain integration and latency characteristics support real-time control and precision measurement in space-constrained designs.
Industrial data acquisition, motor control feedback loops, multi-channel process control, and automatic test equipment represent typical application scenarios. The 14-bit resolution and fast conversion rate suit digitizing sensor outputs, vibration monitoring signals, and closed-loop actuators where rapid settling and low conversion delay are critical. For procurement engineers, the AD7899SRZ-1 is an active, industrial-temperature-range (-40°C to +85°C) device with long-term continuity; it does not carry military or /883-level qualification. Where extended temperature grades or high-reliability screening are required, alternative suffix configurations within the AD7899 family can be assessed to meet those environmental specifications.
