Product details
Overview
AD7677ACPRL from Analog Devices is a 16-bit, 1 MSPS, fully differential successive approximation register (SAR) analog-to-digital converter operating from a single 5 V supply. It delivers ±1 LSB integral nonlinearity, 94 dB typical SNR at 45 kHz, and supports differential input range of ±2.5 V. Its hardware-calibrated architecture enables high-precision data acquisition in medical CT scanners and battery-powered instrumentation.
For engineers reviewing the AD7677ACPRL datasheet, AD7677ACPRL pinout, AD7677ACPRL application, or AD7677ACPRL equivalent, this page provides verified technical context, real-world interface timing modes (Warp/Normal/Impulse), confirmed LFCSP-48 package mapping, and validated alternatives for precision ADC selection in high-speed, low-power, or wide dynamic range systems.
Technical Context
The AD7677ACPRL implements a charge redistribution SAR architecture with on-chip track-and-hold, delivering zero pipeline delay and full 16-bit no-missing-code performance. Its three operational modes-Warp (1 MSPS, 1 µs conversion, requires ≤1 ms inter-conversion interval), Normal (800 kSPS, no timing constraint), and Impulse (666 kSPS, power scaled to throughput)-are selected via dedicated WARP and IMPULSE digital inputs.
It integrates dual-domain power supplies (AVDD/DVDD for analog/digital core, OVDD for I/O interface), supports both straight binary and two's complement output coding via OB/2C, and features configurable serial (2-wire master/slave) or parallel (8-/16-bit) interfaces compatible with 3 V or 5 V logic levels-all within a single monolithic die.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16 bits - guarantees no missing codes across full scale, essential for metrology-grade measurement fidelity. |
| Throughput Rate | 1 MSPS in Warp Mode - enables real-time sampling of signals up to 15.8 MHz bandwidth without aliasing. |
| INL | ±1 LSB max - ensures absolute accuracy ≤76.3 µV over ±2.5 V input range, critical for calibration-critical systems. |
| S/(N+D) | 94 dB typ @ 45 kHz - delivers >15.5 ENOB, supporting high-fidelity spectrum analysis and medical imaging. |
| Power Dissipation | 115 mW @ 1 MSPS; 15 µW @ 100 SPS - scalable consumption allows optimization for mains-powered or coin-cell operation. |
| Analog Input Range | Differential ±2.5 V - supports true bipolar signal acquisition without external level-shifting circuitry. |
| Interface Options | Parallel (8/16-bit) or 2-wire serial - simplifies integration into FPGA, microcontroller, or DSP-based host systems. |
Pinout & Package
AD7677ACPRL is housed in a 48-lead Lead Frame Chip Scale Package (LFCSP), measuring 7 mm × 7 mm × 0.85 mm, with exposed thermal pad for enhanced thermal performance in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN– | Differential analog input pair | Accepts true differential signal up to ±2.5 V; common-mode rejection ≥85 dB at 10 kHz enables noise-immune sensing. |
| REF, REFGND | External reference voltage interface | Supports 2.3 V to (AVDD – 1.85 V); 37 µA max current draw allows use with low-power reference ICs or resistive dividers. |
| WARP, IMPULSE | Mode selection inputs | Hardware-configurable operation mode: Warp (max speed), Impulse (power scaling), or Normal (asynchronous robustness). |
| SER/PAR, OB/2C | Interface configuration controls | Selects serial vs. parallel output and straight binary vs. two's complement coding-no firmware dependency required. |
| BUSY, CNVST | Conversion control & status | BUSY falling edge serves as deterministic data-ready strobe; CNVST falling edge initiates sample-and-hold capture. |
| OVDD, AVDD, DVDD | Independent power domains | Enables mixed-voltage system design: OVDD sets I/O logic level (3 V or 5 V), while AVDD/DVDD remain at 5 V for analog/digital core stability. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay | Immediate result availability after BUSY goes low - eliminates latency-induced phase errors in closed-loop control systems. |
| Three selectable throughput modes | Warp (1 MSPS), Normal (800 kSPS), Impulse (666 kSPS) - allows runtime trade-off between speed, accuracy, and power without changing hardware. |
| Single 5 V supply operation | Eliminates need for dual ±5 V or ±15 V rails - reduces BOM count and simplifies power tree design in portable instruments. |
| Hardware factory calibration | Guarantees AC specs (SNR, THD) and DC specs (gain, offset, linearity) without user calibration - cuts production test time and cost. |
| Pin-to-pin compatibility | Direct upgrade path from AD7664/AD7675/AD7676 - enables drop-in replacement in existing LQFP or LFCSP footprints without layout revision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, high-accuracy SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7676ASTRL | LQFP-48 package only; identical electrical specs and pinout; lacks LFCSP thermal performance. | Better suited for prototyping or legacy board designs using QFP footprints; not optimal for thermally constrained embedded modules. | Choose AD7676ASTRL if reusing existing LQFP layout; AD7677ACPRL preferred for new compact, thermally demanding designs. |
| AD7675ASTRL | Same LQFP-48 package; 0.5 LSB INL (tighter), but limited to 666 kSPS max; no Warp Mode. | Ideal for applications prioritizing ultimate linearity over maximum speed-e.g., calibration standards or static metrology. | Select AD7675ASTRL when ±0.5 LSB INL is mandatory and 1 MSPS is unnecessary; AD7677ACPRL offers speed-flexibility trade-off. |
Compared with AD7676ASTRL and AD7675ASTRL, the AD7677ACPRL uniquely combines LFCSP thermal efficiency, 1 MSPS Warp Mode, and full pin compatibility-making it the optimal choice for next-generation portable, high-density, or thermally sensitive precision ADC deployments.

FAQ
What is the maximum guaranteed sampling rate for the AD7677ACPRL?
The AD7677ACPRL achieves a maximum guaranteed throughput of 1 million samples per second (1 MSPS) in Warp Mode. This mode requires that the time between consecutive conversions does not exceed 1 ms to maintain full specified accuracy-including ±1 LSB INL and 94 dB SNR. In Normal Mode, the device operates reliably at up to 800 kSPS without inter-conversion timing constraints, making it suitable for asynchronous data acquisition where timing predictability is less critical than absolute speed.
Does the AD7677ACPRL require external calibration to meet its datasheet specifications?
No, the AD7677ACPRL is hardware factory calibrated and comprehensively tested by Analog Devices to guarantee all AC parameters-including SNR, THD, and SFDR-as well as DC parameters such as gain, offset, and linearity. This eliminates the need for user-performed calibration in production systems, reducing test time and ensuring consistent performance across units without firmware intervention or external reference trimming.
Can the AD7677ACPRL operate with a 3 V digital interface while maintaining a 5 V analog supply?
Yes, the AD7677ACPRL supports independent voltage domains: AVDD and DVDD are rated for 4.75 V to 5.25 V, while OVDD (I/O interface supply) operates from 2.7 V to 5.25 V. Setting OVDD to 3 V enables direct interfacing with 3 V FPGAs or microcontrollers, while AVDD/DVDD remain at 5 V to preserve analog performance and internal reference stability-no level shifters required.
What package type is used for the AD7677ACPRL, and how does it differ from the AD7677ASTRL?
The AD7677ACPRL uses a 48-lead Lead Frame Chip Scale Package (LFCSP), measuring 7 mm × 7 mm × 0.85 mm with an exposed thermal pad. In contrast, the AD7677ASTRL uses a 48-lead Quad Flatpack (LQFP). Both share identical pinouts and electrical specifications, but the LFCSP offers superior thermal resistance (JA = 26°C/W vs. 91°C/W for LQFP), enabling higher sustained throughput in space-constrained or thermally demanding applications.
How does the Impulse Mode reduce power consumption in the AD7677ACPRL?
In Impulse Mode (activated by setting IMPULSE = HIGH and WARP = LOW), the AD7677ACPRL scales its internal power consumption proportionally to the actual sampling rate. At 100 SPS, typical power dissipation drops to 15 µW-over 7,600× lower than the 115 mW consumed at 1 MSPS. This dynamic scaling is achieved through adaptive clock gating and reduced bias currents, making the AD7677ACPRL ideal for battery-powered devices with intermittent sensing requirements.
