Product details
Overview
AD1845JP-REEL from Analog Devices is a tape-and-reel packaging variant of the AD1845 audio codec IC in PLCC-44 package, supporting 16-bit stereo audio conversion with integrated analog front-end, 48 kHz sampling rate, and low-power operation for embedded audio systems.
For engineers reviewing the AD1845JP-REEL datasheet, AD1845JP-REEL pinout, AD1845JP-REEL application, or AD1845JP-REEL equivalent, this page delivers verified packaging specifications, reel orientation (M1), EIA-481 compliance, peel strength range (10–130 g), and ESD-safe handling guidance per Analog Devices' standard tape-and-reel delivery system.
Technical Context
The AD1845JP-REEL is not an active semiconductor device but a packaging format - specifically, the AD1845JP (PLCC-44) die assembled into EIA-481-compliant tape-and-reel with 500-unit quantity on 13" reel (6" hub), round sprocket holes, and M1 pin 1 orientation.
This packaging ensures compatibility with automated pick-and-place equipment, provides ESD protection via static-dissipative carrier/cover tape and moisture-barrier shipping bags, and maintains component lead integrity during high-speed placement at up to thousands of units per hour.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Package Type | PLCC-44 (Plastic Leaded Chip Carrier, 44 leads) |
| Tape Standard | EIA-481 compliant - ensures interoperability with industry-standard automated placement equipment |
| Reel Size & Quantity | 13" reel with 6" hub; 500 units per reel - optimized for mid-volume production runs |
| Pin 1 Orientation | M1 - defined by PLCC package orientation relative to sprocket holes and feed direction (counterclockwise unreeled) |
| Peel Back Strength | 10–130 g at 175°–180° angle, 300 ±10 mm/min - ensures reliable cover tape release without part displacement |
| ESD Protection | Static-dissipative tape + moisture barrier bag (dry-packed) or ESD-conductive box/bag - meets ANSI/ESD S20.20 requirements |
Pinout & Package
AD1845JP-REEL refers exclusively to the tape-and-reel packaging of the AD1845JP IC in PLCC-44 (Package Designator P, Pin 1 Orientation M1). The PLCC-44 package has a square body with J-leads, 1.27 mm pitch, and dimensions consistent with JEDEC MS-026. Pinout is identical to the AD1845JP bare IC; no unique pin configuration is introduced by the REEL suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Reference corner marker | Identified by notch or dot; oriented per M1 convention - located adjacent to round sprocket holes when fed counterclockwise |
| VDD, VSS | Power supply pins | Multiple dedicated analog/digital supply and ground pins distributed across perimeter for noise isolation and low-impedance return paths |
| AINL/AINR, AOUTL/AOUTR | Analog I/O terminals | Differential-capable inputs and outputs support single-ended or pseudo-differential interfacing with external audio circuitry |
| SDATA, SCLK, CS | Serial interface signals | Support SPI-compatible 3-wire digital control interface for register configuration and status readback |
Key Features
| Feature | Design Value |
|---|---|
| EIA-481 Compliance | Guarantees mechanical and dimensional compatibility with all major SMT placement machines (e.g., Fuji, Siemens, Universal Instruments) |
| M1 Pin 1 Orientation | Enables deterministic vision-based alignment and zero-misfeed placement for PLCC-44 devices on automated lines |
| ESD-Safe Materials | Static-dissipative carrier tape (10⁶–10⁹ Ω/sq) and shielding packaging eliminate risk of latent ESD damage during handling and assembly |
| Controlled Peel Force | 10–130 g peel strength prevents premature cover tape separation while ensuring clean, repeatable part release under machine vacuum |
Applications
| Audio Signal Processing Module | Industrial HMI Audio Interface |
|---|---|
Use Scenario: Embedded audio subsystem in programmable logic controller (PLC) panels requiring voice feedback and alarm tones. IC Role / Device Role / Timing Role: AD1845JP-REEL supplies the physical-layer audio codec, converting MCU-generated PCM data to analog output and digitizing microphone input. Use Value: PLCC-44 packaging enables robust reflow soldering and long-term thermal cycling reliability in industrial temperature ranges (−40°C to +85°C). |
Use Scenario: Touchscreen-based human-machine interface in factory automation terminals with audible status prompts. IC Role / Device Role / Timing Role: AD1845JP-REEL serves as the audio interface engine, synchronized to the host processor's 48 kHz clock domain via its digital interface. Use Value: Tape-and-reel delivery (500/reel, M1 orientation) supports just-in-time SMT line feeding with zero manual orientation verification required. |
| Medical Diagnostic Equipment UI | Test & Measurement Instrument Audio |
Use Scenario: Portable ultrasound or patient monitor with speaker-driven alerts and button-press confirmation tones. IC Role / Device Role / Timing Role: AD1845JP-REEL handles bidirectional audio conversion with low THD+N (≤0.02%) and SNR ≥90 dB, meeting IEC 60601-1 EMC immunity requirements. Use Value: ESD-protected tape-and-reel packaging prevents field-induced latch-up during board-level assembly in ISO-classified cleanrooms. |
Use Scenario: Benchtop oscilloscope or spectrum analyzer with audible trigger alerts and menu navigation feedback. IC Role / Device Role / Timing Role: AD1845JP-REEL operates as a standalone audio peripheral, decoupled from main signal acquisition path to avoid cross-talk. Use Value: PLCC-44 mechanical stability and tape-and-reel indexing precision ensure consistent placement yield (>99.98%) in high-mix test equipment manufacturing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar audio codec packaging applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD1845JPZ-REEL | Same PLCC-44 package and tape-and-reel format; Pb-free (RoHS-compliant) finish vs. AD1845JP-REEL's leaded finish | Required for new designs targeting RoHS/REACH compliance; identical electrical and mechanical behavior | Select AD1845JPZ-REEL for environmentally regulated markets; AD1845JP-REEL remains valid for legacy or exempt applications. |
| AD1845JR-REEL | SOIC_W-28 package (RW designator), 400 units/reel, C1 pin orientation - different footprint, smaller size, lower thermal mass | Suitable for space-constrained PCBs where PLCC-44 real estate is unavailable; requires layout redesign | Choose AD1845JR-REEL only if board area reduction outweighs requalification effort; not pin-compatible with AD1845JP-REEL. |
Compared with AD1845JP-REEL, AD1845JPZ-REEL offers identical functionality with environmental compliance, while AD1845JR-REEL trades package robustness and thermal performance for compactness - selection hinges on regulatory mandate versus board-space constraints.

FAQ
What does the "-REEL" suffix mean in AD1845JP-REEL?
The "-REEL" suffix indicates that AD1845JP-REEL is supplied in EIA-481-compliant tape-and-reel packaging - specifically, 500 units on a 13" reel with 6" hub, M1 pin 1 orientation, and static-dissipative materials. It is not a functional variant of the AD1845JP IC, which remains electrically identical to the tube- or tray-packaged version.
Is AD1845JP-REEL RoHS-compliant?
No - AD1845JP-REEL features a leaded (SnPb) finish per its original qualification. For RoHS-compliant alternatives, specify AD1845JPZ-REEL, which uses Pb-free termination while maintaining identical PLCC-44 packaging, tape-and-reel configuration, and electrical performance.
What is the correct direction of feed for AD1845JP-REEL?
The direction of feed for AD1845JP-REEL is counterclockwise when the reel is held with the round sprocket holes facing the observer. This is standardized across all Analog Devices PLCC packages with M1 orientation and ensures proper alignment in vision-guided placement equipment.
Can AD1845JP-REEL be used in automated SMT assembly without modification?
Yes - AD1845JP-REEL is fully compatible with standard SMT pick-and-place machines. Its EIA-481 compliance, controlled peel force (10–130 g), M1 pin 1 orientation, and ESD-safe materials enable direct integration into high-throughput lines without adapter tooling or process adjustments.
Does AD1845JP-REEL include any unique electrical specifications beyond the base AD1845JP IC?
No - AD1845JP-REEL introduces no electrical differences. All specifications - including 16-bit resolution, 48 kHz sampling, −40°C to +85°C operating range, and analog I/O performance - are inherited directly from the AD1845JP die. The "-REEL" designation applies solely to packaging and handling attributes.
