AD4001BRMZ-RL7

Analog To Digital Converters (ADC) Overview

The AD4001BRMZ-RL7 is a 16-bit, 2 MSPS precision successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 1.8 V supply with a separate digital interface voltage range of 1.71 V to 5.5 V. The device features a differential analog input range of ±VREF, where VREF ranges from 2.4 V to 5.1 V. Key performance metrics include a maximum integral nonlinearity error of ±0.4 LSB and a signal-to-noise ratio of 96.2 dB at 1 kHz input frequency. It utilizes an SPI-compatible serial interface and is housed in a 10-lead MSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Easy Drive architecture with high-Z mode reduces input current to 0.5 μA/MSPS and extends acquisition phase to ≥79% of cycle time at 1 MSPS.
• Input span compression allows operation from common supply rails without negative supplies while preserving full ADC code range.
• Integrated input overvoltage clamp protection sinks up to 50 mA to protect against overvoltage events.
• Supports multiple serial interface modes including SPI, QSPI, MICROWIRE, DSP, and daisy-chain configurations.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging quantity of 1000 units as indicated in distributor specifications. Confirm that the BRMZ variant matches the required temperature grade and package type for the target application environment before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 2 MSPS throughput are required with low power consumption. Ensure the system design accommodates the 1.8 V analog supply and compatible logic levels for the VIO pin. Consider the Easy Drive features if minimizing external driver amplifier complexity is a priority.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD4001/AD4005 family of precision SAR ADCs. The AD4001 provides 2 MSPS throughput, while the AD4005 offers 1 MSPS. Both share similar architectural features and pinouts, facilitating design flexibility within high-performance data acquisition applications requiring low noise and high accuracy.

Analog To Digital Converters (ADC) Replacement Considerations

The AD4003, AD4007, and AD4011 are pin-compatible members of the same family but offer different resolutions or throughput rates. Verify that the replacement part's resolution and sampling speed meet the specific system requirements before substitution.
