AD4001BCPZ-RL7

Analog To Digital Converters (ADC) Overview

The AD4001BCPZ-RL7 is a 16-bit, 2 MSPS precision successive approximation register (SAR) analog-to-digital converter from Analog Devices. It operates on a single 1.8 V analog supply with a 1.71 V to 5.5 V digital interface supply. Key electrical parameters include a maximum integral nonlinearity of ±0.4 LSB, a signal-to-noise ratio of 96.2 dB at 1 kHz input frequency, and a total harmonic distortion of −123 dB. The device features an Easy Drive architecture with reduced input kickback and current, eliminating the need for dedicated driver amplifiers in many applications.

Analog To Digital Converters (ADC) Feature Summary

• Easy Drive Architecture: Reduces input current to 0.5 μA/MSPS and extends acquisition phase to ≥79% of cycle time at 1 MSPS.
• High Performance: Delivers 16-bit resolution with no missing codes, 96.2 dB SNR, and 122 dB SFDR.
• Flexible Interface: Supports SPI, QSPI, MICROWIRE, and DSP-compatible serial interfaces with daisy-chain capability.
• Input Protection: Includes input span compression for single-supply operation and overvoltage clamp protection sinking up to 50 mA.

Analog To Digital Converters (ADC) Applications

• Automated test equipment
• Precision data acquisition systems
• Medical equipment
• Battery-powered equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the design requirements, as the AD4001 series is available in both LFCSP and MSOP packages. Confirm that the specific suffix indicates the reel packaging format intended for automated assembly processes. Ensure the voltage reference range of 2.4 V to 5.1 V aligns with the system's reference source capabilities.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high accuracy and moderate speed are required without external driver amplifiers. The AD4001 supports throughput rates up to 2 MSPS, whereas the AD4005 variant is limited to 1 MSPS. Consider the power consumption scaling linearly with throughput, which ranges from 80 μW at 10 kSPS to 16 mW at 2 MSPS.

Analog To Digital Converters (ADC) Part Context

The AD4001 belongs to the PulSAR family of SAR ADCs. It is pin-compatible with the AD4003, AD4007, and AD4011 devices, facilitating design upgrades or changes in performance specifications within the same footprint. The BC suffix typically denotes the industrial temperature range extension to +125°C.

Analog To Digital Converters (ADC) Replacement Considerations

The AD4005 offers identical pinout and functionality but is limited to a 1 MSPS sampling rate. Other members of the pin-compatible family include the AD4003 and AD4011, which may offer different performance trade-offs such as lower power or higher speed.
