Product details
Overview
AD9283BRS-RL80 from Analog Devices is an 8-bit, 80 MSPS monolithic analog-to-digital converter with on-chip track-and-hold, internal 1.25 V reference, and single 3.0 V supply operation. It delivers 46.5 dB SNR at 41 MHz input frequency, 475 MHz analog bandwidth, and 90 mW power dissipation at full rate-designed for portable test equipment requiring high-speed digitization with minimal external components.
For engineers reviewing the AD9283BRS-RL80 datasheet, AD9283BRS-RL80 pinout, AD9283BRS-RL80 application, or AD9283BRS-RL80 equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and two confirmed alternative parts for low-power, 8-bit sampling ADC selection in battery-powered instrumentation and digital oscilloscope front-ends.
Technical Context
The AD9283BRS-RL80 implements a bit-per-stage pipeline ADC architecture with switch-capacitor techniques, where five stages resolve the 5 MSBs and a flash converter encodes the 3 LSBs. Its on-chip track-and-hold operates with 5 ps rms aperture jitter and supports single-ended or differential analog inputs up to ±512 mV p-p.
Digital outputs use offset binary coding, are TTL/CMOS compatible, and driven from a separate VDD pin (2.5 V–3.6 V) to enable interfacing with mixed-voltage logic. The ENCODE input accepts TTL/CMOS-level clocks with 4.3 ns minimum pulse width high, and power-down mode reduces consumption to 4.2 mW while placing outputs in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit-supports 256 discrete amplitude levels for medium-fidelity signal capture in cost-sensitive measurement systems. |
| Sampling Rate | 80 MSPS-enables Nyquist-limited acquisition of signals up to 40 MHz without aliasing in real-time waveform capture. |
| SNR @ 41 MHz | 46.5 dB-ensures usable dynamic range for digitizing RF IF signals or fast transients in handheld scopemeters. |
| Analog Bandwidth | 475 MHz-preserves signal integrity for wideband inputs including harmonics and fast edges without attenuation. |
| Power Dissipation | 90 mW at 80 MSPS-meets thermal and battery-life constraints in compact, uncooled portable instruments. |
| Input Range | ±512 mV p-p-matches standard 1 V p-p test signal sources and simplifies front-end gain staging. |
| Reference | On-chip 1.25 V ±130 ppm/°C-eliminates need for external voltage reference ICs and reduces BOM count. |
Pinout & Package
AD9283BRS-RL80 is housed in a 20-lead SSOP (Shrink Small Outline Package), RS-20 footprint (7.9 mm × 4.4 mm), rated for –40°C to +85°C industrial temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PWRDWN) | Power-down control input | Logic HIGH disables conversion and places all D7–D0 outputs in high-impedance state; enables rapid system-level power gating. |
| 2 (VREF OUT) | Internal reference output | Provides 1.25 V ±130 ppm/°C reference; requires 0.1 µF bypass capacitor to GND for noise suppression and stability. |
| 3 (VREF IN) | Reference input | Accepts internal VREF OUT (via strap) or external reference; full-scale range scales linearly with applied voltage. |
| 4, 9, 16 (GND) | Analog/digital ground terminals | Three dedicated GND pins minimize ground bounce and isolate analog return paths from digital switching noise. |
| 5, 8 (VD) | Analog power supply | Supplies 2.7 V–3.6 V to analog core; decoupling required near pins to maintain SNR performance at 80 MSPS. |
| 6, 7 (AIN, AIN) | Differential analog input | Supports true differential or single-ended operation; common-mode range ±200 mV allows flexible dc biasing. |
| 10 (ENCODE) | Sampling clock input | TTL/CMOS-compatible; rising-edge triggered; 4.3 ns minimum tEH ensures reliable latching at 80 MSPS. |
| 11–14, 17–20 (D7–D0) | Parallel digital outputs | Offset binary coded; driven from VDD (2.5 V–3.6 V) to interface directly with FPGA or microcontroller I/O banks. |
| 15 (VDD) | Digital output power supply | Independent supply rail enables level-shifting to match host logic voltage without level translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9283BRS-100 | Higher 100 MSPS max sampling rate; identical pinout, package, and feature set; 5 mW higher active power at full rate. | Required only when Nyquist zone extends beyond 40 MHz (e.g., 50 MHz IF digitization); otherwise over-spec'd for 80 MSPS use cases. | Select AD9283BRS-100 only if design mandates headroom above 80 MSPS; AD9283BRS-RL80 offers optimal balance of speed, power, and cost for most portable instruments. |
| MAX1183BCUI+ | 8-bit, 80 MSPS ADC from Maxim Integrated; uses external reference; 100 mW typical power; different 24-pin TSSOP package and pin assignment. | Suitable for designs already using Maxim timing/power ecosystem; requires additional reference IC and board redesign due to non-pin-compatible layout. | Choose MAX1183BCUI+ only when leveraging existing Maxim evaluation tools or multi-ADC platform reuse; AD9283BRS-RL80 provides faster time-to-test with integrated reference and known SSOP footprint. |
Compared with AD9283BRS-100, the AD9283BRS-RL80 trades 20 MSPS headroom for lower power and identical cost-making it more efficient for fixed 80 MSPS applications. Against MAX1183BCUI+, it offers pin compatibility, integrated reference, and proven layout reuse across Analog Devices' AD928x family, reducing validation effort.

FAQ
What is the maximum analog input frequency supported by the AD9283BRS-RL80 without aliasing?
The AD9283BRS-RL80 supports a maximum analog input frequency of 40 MHz when operated at its rated 80 MSPS sampling rate, satisfying the Nyquist–Shannon criterion. Its 475 MHz analog bandwidth ensures minimal amplitude roll-off and phase distortion within this band, preserving signal fidelity for fast transient capture in oscilloscope and scopemeter applications.
Does the AD9283BRS-RL80 require an external voltage reference?
No, the AD9283BRS-RL80 includes a factory-trimmed 1.25 V on-chip reference (VREF OUT) with ±130 ppm/°C tempco, eliminating the need for external reference ICs in most applications. Pins 2 (VREF OUT) and 3 (VREF IN) are strapped together for internal reference use; external reference is optional for custom full-scale adjustment.
How does the power-down mode affect the digital outputs of the AD9283BRS-RL80?
In power-down mode (PWRDWN = HIGH), the AD9283BRS-RL80 disables internal conversion circuitry and drives all D7–D0 digital outputs to high-impedance state-preventing bus contention and reducing system-level power draw to 4.2 mW. Recovery to full operation requires approximately 15 encode cycles before valid data appears.
What logic family is compatible with the AD9283BRS-RL80 digital interface?
The AD9283BRS-RL80 digital outputs are TTL/CMOS compatible and support interfacing with 2.5 V or 3.3 V logic families via the dedicated VDD pin (Pin 15). Input thresholds meet standard TTL levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and output swing ranges from 0.05 V to 2.95 V ensure robust noise margins in mixed-signal systems.
Can the AD9283BRS-RL80 operate with a 2.7 V supply voltage?
Yes, the AD9283BRS-RL80 is fully specified for operation across 2.7 V to 3.6 V on both VD (analog) and VDD (digital output) supplies. At 2.7 V, it maintains 80 MSPS sampling capability, 46.5 dB SNR at 41 MHz, and 90 mW typical power dissipation-enabling direct integration into single-cell Li-ion or regulated 2.8 V systems without voltage boosting.
