AD976BNZ

Analog To Digital Converters (ADC) Overview

The AD976BNZ is a monolithic 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes successive approximation register (SAR) architecture to achieve a throughput of 200 kSPS. The device operates on a single +5 V supply for both analog and digital domains, consuming a maximum power dissipation of 120 mW. Key electrical specifications include an integral nonlinearity (INL) error of ±3 LSB and a signal-to-noise ratio (SNR) of 85 dB. It features a parallel data interface and supports external or internal reference configurations. The component is housed in a 28-lead plastic dual in-line package (PDIP) suitable for through-hole mounting.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 16-bit SAR ADC with a built-in clock generator and on-chip reference options.
• Supports flexible input voltage ranges including 0 V to +4 V, 0 V to +5 V, and 0 V to +10 V via external resistive networks.
• Includes a dedicated power-down mode to significantly reduce standby power consumption.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Portable instrumentation and battery-operated measurement devices.
• Communication transmit channels and base station equipment.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BNZ' against the official Analog Devices datasheet to confirm pinout compatibility and temperature range specifications. Ensure that the required input voltage range matches the external circuit design, as the AD976 supports multiple ranges. Confirm availability status, as this component may be subject to end-of-life restrictions or limited stock conditions from authorized distributors.

Analog To Digital Converters (ADC) Selection Notes

Select the AD976BNZ when a single-channel, 16-bit resolution is required at sampling rates up to 200 kSPS. This component is appropriate for designs constrained by a single +5 V supply rail. Consider alternative models within the AD97x family if higher channel counts or different interface types such as serial communication are necessary for the system architecture.

Analog To Digital Converters (ADC) Part Context

The AD976 belongs to the AD97x series of high-performance data acquisition systems from Analog Devices. This family is designed for applications demanding low power consumption and high accuracy. The AD976 specifically addresses the need for a complete 16-bit solution with integrated timing and reference capabilities, distinguishing it from simpler ADCs that require external support components.

Analog To Digital Converters (ADC) Replacement Considerations

The AD976ABNZ is a verified substitute offering identical functional specifications and pinout compatibility. Both variants share the same 16-bit resolution, 200 kSPS speed, and PDIP-28 packaging. Verify that the operating temperature range requirements align with the specific grade of the replacement part.
