Key Features
- 16-bit successive approximation architecture with 8 µs maximum conversion time enables high-throughput precision data acquisition
- Wide ±10 V bipolar analog input range (−10 V to +10 V) eliminates the need for external signal attenuation in industrial measurement
- 0.0031% maximum linearity error in a through-hole 28-pin DIP package simplifies prototyping and legacy system integration
Applications
The AD976BNZ is used in precision industrial data acquisition systems that require 16-bit resolution with bipolar input ranges up to ±10 V. It suits signal conditioning boards in test and measurement equipment, process control instrumentation, and legacy through-hole designs where board-level prototyping is prioritized. Its fast 8 µs conversion time also supports multi-channel scanning applications in laboratory and medical instrumentation.

Frequently Asked Questions
What is the maximum conversion time of the AD976BNZ and how does it affect throughput in a scanning system?
The AD976BNZ achieves a maximum conversion time of 8 µs, enabling sample rates up to approximately 125 kSPS in single-channel operation. In a multi-channel scanning system, the effective per-channel rate decreases proportionally with the number of channels, so a 4-channel scan yields about 31 kSPS per channel, suitable for industrial process monitoring at 16-bit resolution.
For a ±10 V industrial sensor interface, how does the AD976BNZ handle the full bipolar input range?
The AD976BNZ accepts analog inputs from −10 V to +10 V directly, covering the full 20 V bipolar range common in industrial 4–20 mA transmitter and voltage output sensors. This eliminates external attenuation or level-shift circuitry, and the 16-bit resolution maps the 20 V span to LSB steps of approximately 305 µV for precise measurement.
When is the AD976BNZ a practical alternative to surface-mount 16-bit ADCs for prototyping or repair applications?
The AD976BNZ in a 28-pin DIP package is ideal for breadboard prototyping, lab bench setups, and field repair of legacy industrial equipment where surface-mount rework tools are unavailable. Its through-hole form factor supports socketed installation, allowing easy component swaps during development or maintenance while retaining full 16-bit, 8 µs conversion performance.
What linearity specification does the AD976BNZ guarantee and why does it matter for precision measurement?
The AD976BNZ guarantees a maximum linearity error of 0.0031%, equivalent to roughly ±2 LSB at 16-bit resolution. This tight specification is critical in weighing systems, chromatography, and precision voltage measurement where nonlinearity directly translates to measurement error, ensuring that the ADC does not introduce systematic offsets across the full ±10 V input span.
