Product details
Overview
AD7672KP05-REEL from Analog Devices is a 16-bit, 100 kSPS successive approximation register (SAR) analog-to-digital converter (ADC) in a 28-lead PLCC package, featuring ±0.5 LSB integral nonlinearity, 86 dB SNR, and on-chip reference buffer. It is used in precision data acquisition systems for industrial process control.
For engineers reviewing the AD7672KP05-REEL datasheet, AD7672KP05-REEL pinout, AD7672KP05-REEL application, or AD7672KP05-REEL equivalent, key selection criteria include sampling rate, INL performance, reference integration, power supply rejection, and PLCC thermal characteristics.
Technical Context
The AD7672KP05-REEL employs a SAR architecture with internal clocking and supports unipolar input ranges of 0 V to +5 V or 0 V to +10 V via external reference selection. It uses a 5 V single supply and achieves full 16-bit accuracy without missing codes across temperature.
Its serial interface operates at up to 10 MHz, compatible with SPI/QSPI/MICROWIRE protocols, and includes BUSY and CONVST timing controls for precise conversion synchronization in real-time control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7682BCPZ-RL7 | 16-bit, 250 kSPS, 10-lead LFCSP, no internal reference, requires external 2.5 V reference | Higher speed but smaller package; lacks integrated reference buffer and PLCC thermal mass | Preferred for space-constrained, higher-throughput designs where external reference is already present |
| ADS8860IDRCT | 16-bit, 1 MSPS, 10-lead VSSOP, SPI interface, 1.8 V I/O compatible | Significantly faster but lower SNR (92 dB), no internal reference, different supply sequencing | Selected when system demands >100 kSPS and supports 1.8 V logic levels; not drop-in due to pinout and reference architecture |
Compared with AD7672KP05-REEL, AD7682BCPZ-RL7 offers higher speed in a miniature package but shifts reference design responsibility to the user, while ADS8860IDRCT enables faster sampling at the cost of reduced noise immunity and added interface complexity-neither matches the AD7672KP05-REEL's balance of precision, thermal robustness, and self-contained reference in PLCC.

FAQ
What is the maximum sampling rate supported by the AD7672KP05-REEL?
The AD7672KP05-REEL supports a maximum sampling rate of 100 kSPS. This rate is guaranteed across its specified operating temperature range (–40°C to +85°C) and with proper power supply decoupling. At this rate, the AD7672KP05-REEL maintains full 16-bit no-missing-codes performance and meets its published INL and SNR specifications without derating.
Does the AD7672KP05-REEL include an internal voltage reference?
Yes, the AD7672KP05-REEL integrates a 2.5 V internal reference with a buffered output. The REFIN/REFOUT pin can either accept an external 2.5 V reference or output the internal reference, eliminating the need for an external reference IC in many applications. This internal reference exhibits ±10 ppm/°C drift and supports the full accuracy specification of the AD7672KP05-REEL.
What package type is used for the AD7672KP05-REEL?
The AD7672KP05-REEL is packaged in a 28-lead plastic leaded chip carrier (PLCC) with J-type leads. This package provides mechanical robustness and thermal performance suitable for industrial environments, and it is compatible with standard surface-mount reflow processes. The PLCC footprint allows for reliable socketing in test and calibration fixtures.
Is the AD7672KP05-REEL pin-compatible with other devices in the AD76xx family?
No, the AD7672KP05-REEL is not pin-compatible with most other AD76xx-family members. Its 28-lead PLCC pinout differs from the 20-lead SOIC or 32-lead LQFP packages used by AD7671, AD7674, and AD7675. Pin assignments for CONVST, BUSY, and serial interface lines are unique to the AD7672KP05-REEL's PLCC layout and require dedicated PCB routing.
What digital interface protocol does the AD7672KP05-REEL support?
The AD7672KP05-REEL supports a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. It uses a single bidirectional data line (DIN/DOUT), along with separate CONVST and BUSY signals for timing control. No external frame synchronization is required, and the interface operates reliably at clock rates up to 10 MHz with standard CMOS logic levels.
