Product details
Overview
AD7884BPZ-REEL from Analog Devices is a 16-bit monolithic sampling analog-to-digital converter (ADC) with internal sample-and-hold, 5.3 µs conversion time, ±5 V or ±3 V input ranges, and 166 kSPS throughput. It operates from ±5 V supplies with a 3 V reference and delivers 84 dB SNR in ±5 V input mode - used in high-precision data acquisition systems requiring fast, accurate digitization of bipolar analog signals.
For engineers reviewing the AD7884BPZ-REEL datasheet, AD7884BPZ-REEL pinout, AD7884BPZ-REEL application, or AD7884BPZ-REEL equivalent, key selection considerations include its 16-bit parallel output architecture, two-pass flash conversion topology, bipolar zero error of ±0.15% FSR max, integral nonlinearity of ±0.0075% FSR, and PLCC-44 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The AD7884BPZ-REEL implements a two-pass flash ADC architecture: first pass captures 9 MSBs via a 9-bit ADC and feeds them to an on-chip 16-bit DAC; second pass digitizes the residue error amplified by the on-chip residue amplifier. This enables 16-bit resolution at 166 kSPS while maintaining ±0.0075% FSR INL and 84 dB SNR.
It features independent analog/digital power domains (AVDD/AVSS and VDD/VSS), dual reference force/sense pins (VREF+F/VREF+S), and dedicated analog ground sense/force paths (AGNDS/AGNDF) to minimize ground-induced linearity errors. Conversion is initiated asynchronously via CONVST, with BUSY signaling completion and CS/RD controlling 16-bit parallel readout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16 bits - guarantees no missing codes across full scale; minimum resolution for monotonicity. |
| Conversion Time | 5.3 µs max - defines minimum inter-conversion interval; enables 166 kSPS sustained throughput. |
| Input Range | ±5 V or ±3 V - selectable via external pin configuration; supports standard industrial sensor outputs. |
| Integral Nonlinearity | ±0.0075% FSR max - limits end-point accuracy error to < ±1 LSB at 16-bit scale (±152.6 µV in ±5 V mode). |
| Signal-to-Noise+Distortion | 84 dB min at 1 kHz, ±5 V input - corresponds to ~13.3 effective bits; validates dynamic fidelity for precision instrumentation. |
| Power Dissipation | 325 mW max - typical 250 mW at ±5 V supplies; requires thermal management in dense PCB layouts. |
| Bipolar Zero Error | ±0.15% FSR max - introduces up to ±7.5 mV offset at midscale in ±5 V mode; impacts dc-coupled calibration. |
Pinout & Package
The AD7884BPZ-REEL is housed in a 44-lead Plastic Leaded Chip Carrier (PLCC) package with lead pitch 0.05 inches and body size 16.59 mm × 16.59 mm. Pin 1 is marked by a corner notch; pins are arranged in a square grid with index mark at top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DB0–DB15 | 16-bit parallel data output | Twos-complement digital representation of converted analog input; latched and stable after RD pulse. |
| CONVST | Asynchronous conversion start | Rising-edge triggered; initiates sample-and-hold hold mode and starts internal conversion sequence. |
| CS, RD | Read control interface | Active-low chip select and read strobe; together enable byte-wide or full-word read access to output latch. |
| BUSY | Conversion status indicator | Active-low open-drain output; goes low at CONVST edge and returns high upon result availability. |
| VREF+S / VREF+F | Reference sense/force inputs | Accept 3 V reference; sense pin monitors reference voltage at device input, force pin drives internal reference node. |
| ±5VINF / ±5VINS | Analog input force/sense (±5 V range) | Configure for ±5 V differential input: INF connects to signal source, INS returns to AGND via buffer amplifier. |
| AGNDS / AGNDF | Analog ground sense/force | Separate sense/force paths for 9-bit ADC section; must be buffered (not shorted) to maintain specified INL and gain TC. |
Key Features
| Feature | Design Value |
|---|---|
| Two-pass flash architecture | Enables 16-bit resolution at 166 kSPS without pipeline latency or calibration overhead. |
| Internal oscillator | Eliminates need for external clock source; ensures deterministic timing independent of system clock jitter. |
| Dual analog/digital supply domains | AVDD/AVSS and VDD/VSS separation reduces digital switching noise coupling into analog signal path. |
| Configurable ±3 V / ±5 V input range | Hardware-selectable via pin strapping; avoids external gain stages for common industrial sensor interfaces. |
| On-chip 16-bit laser-trimmed DAC | Provides precise feedback for residue amplification; ensures ±0.0075% FSR INL without system-level trimming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed 16-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7884AQ | Same core architecture and specs, but in 40-lead CERDIP package; higher θJA (44.5°C/W vs 47.7°C/W) and no REEL packaging. | Preferred for through-hole prototyping or legacy CERDIP-compatible sockets; lacks tape-and-reel support for SMT production. | Select AD7884AQ only when CERDIP mechanical fit or hand-soldering is required; AD7884BPZ-REEL is optimal for automated assembly. |
| AD7674ASTZ | SAR architecture (not flash); 18-bit resolution, 100 kSPS max, serial SPI interface, no internal reference; requires external 5 V reference. | Better resolution but lower speed; suited for high-accuracy, lower-throughput applications where serial interface simplifies routing. | Choose AD7674ASTZ when >16-bit resolution is mandatory and 100 kSPS suffices; AD7884BPZ-REEL remains superior for 166 kSPS with parallel interface. |
Compared with AD7884AQ and AD7674ASTZ, the AD7884BPZ-REEL uniquely combines 166 kSPS throughput, 16-bit parallel output, and PLCC-44 tape-and-reel packaging - making it the only option supporting high-volume SMT production of industrial DAQ modules requiring both speed and ease of integration.

FAQ
What is the operating temperature range for the AD7884BPZ-REEL?
The AD7884BPZ-REEL is rated for operation from –40°C to +85°C, matching the industrial temperature grade defined in the AD7884/AD7885 datasheet Revision E. This range is validated across all electrical specifications including INL, SNR, and conversion time, and applies specifically to the BP-grade version in PLCC-44 packaging.
Does the AD7884BPZ-REEL require an external clock source?
No, the AD7884BPZ-REEL contains an internal oscillator that controls the conversion timing sequence. External clocking is not supported or required; conversion is initiated solely by the CONVST signal, and BUSY indicates completion. This eliminates clock distribution complexity and jitter sensitivity in the AD7884BPZ-REEL design.
How is the ±3 V input range configured on the AD7884BPZ-REEL?
The ±3 V input range on the AD7884BPZ-REEL is selected by connecting ±3VINF and ±3VINS to the signal source and grounding ±5VINF and ±5VINS to AGND. The internal resistor network then provides a gain of –1, scaling the input to the required 0 V to –3 V range for the 9-bit ADC stage - as confirmed in the Functional Block Diagram and Pin Function Descriptions.
What is the significance of separate AGNDS and AGNDF pins on the AD7884BPZ-REEL?
AGNDS (analog ground sense) and AGNDF (analog ground force) provide Kelvin connections for the 9-bit ADC's ground return path. Buffering AGNDS with a low-offset op amp (e.g., AD817) and driving AGNDF from that buffer maintains ground integrity - preventing degradation of INL, gain TC, and bipolar zero error. Direct shorting degrades dc specs, though dynamic performance remains largely unaffected.
Can the AD7884BPZ-REEL interface directly with a 3.3 V microcontroller bus?
No - the AD7884BPZ-REEL logic inputs (CS, RD, CONVST) require VDD = +5 V ±5%, and its DB0–DB15 outputs swing from 0 V to VDD (≈5 V). Direct connection to a 3.3 V microcontroller risks overvoltage damage. Level translation (e.g., 74LVC4245) or a 5 V-tolerant MCU interface is mandatory for safe operation of the AD7884BPZ-REEL.
