Product details
Overview
AD9283BRS-RL50 from Analog Devices is an 8-bit, 50 MSPS monolithic analog-to-digital converter with on-chip track-and-hold, single 3.0 V supply operation (2.7–3.6 V), 475 MHz analog bandwidth, and 1 Vp-p input range. It delivers 46.5 dB SNR at 41 MHz input frequency and supports power-down mode consuming only 4.2 mW - ideal for battery-powered digital oscilloscopes and hand-held scopemeters.
For engineers reviewing the AD9283BRS-RL50 datasheet, AD9283BRS-RL50 pinout, AD9283BRS-RL50 application, or AD9283BRS-RL50 equivalent, key selection considerations include its SSOP-20 package, TTL/CMOS-compatible digital outputs, internal 1.25 V reference, offset binary coding, and guaranteed no-missing-codes performance across –40°C to +85°C.
Technical Context
The AD9283BRS-RL50 implements a bit-per-stage pipeline ADC architecture with switch-capacitor techniques, where five stages resolve the 5 MSBs and a flash sub-converter encodes the 3 LSBs. Its on-chip track-and-hold operates with 5 ps rms aperture jitter and supports both differential and single-ended analog inputs biased at 0.3 × VD.
Digital outputs are latched with four-pipeline latency, driven by a separate VDD rail (2.5–3.6 V) for flexible logic interfacing. The ENCODE input is fully TTL/CMOS compatible with 1.5 V threshold, and power-down activation (logic HIGH on PWRDWN) places outputs in high-impedance state within two clock cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - fixed word length enabling direct interface with 8-bit microcontrollers and FPGA data paths without bit-width conversion. |
| Sampling Rate | 50 MSPS - maximum sustained conversion rate defining real-time bandwidth limit of 25 MHz (Nyquist) for baseband signal capture. |
| Analog Bandwidth | 475 MHz - enables accurate digitization of fast-rising edges and wideband RF IF signals up to ~100 MHz without significant amplitude roll-off. |
| SNR @ 41 MHz | 46.5 dB - quantifies usable dynamic range for medium-frequency input tones; corresponds to ~7.5 effective bits (ENOB) at that frequency. |
| Power Dissipation | 80 mW typical at 50 MSPS - low active power enables thermal management in compact, unventilated portable instruments. |
| Power-Down Power | 4.2 mW - reduces system standby power by >94%, critical for battery life extension during idle intervals in handheld test equipment. |
| Input Range | ±512 mV p-p (1.024 V full-scale) - matches standard 50 Ω source impedance and simplifies front-end gain staging with common op-amps. |
Pinout & Package
The AD9283BRS-RL50 is housed in a 20-lead shrink small outline plastic package (SSOP, RS-20), 7.9 mm × 4.4 mm footprint, 0.65 mm lead pitch, specified for industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWRDWN (Pin 1) | Power-down control input | Logic HIGH forces ADC into low-power state; digital outputs enter high-impedance, reducing system bus loading and leakage current. |
| VREF OUT (Pin 2) | Internal reference voltage output | Supplies nominally 1.25 V ±130 ppm/°C; must be bypassed with 0.1 µF capacitor to GND for stable reference operation. |
| VREF IN (Pin 3) | Reference voltage input | Accepts external reference or connects to Pin 2 for internal reference use; full-scale range scales linearly with applied voltage. |
| GND (Pins 4, 9, 16) | Analog/digital ground return | Three dedicated ground pins minimize ground bounce and improve PSRR; require low-inductance PCB connection to common ground plane. |
| VD (Pins 5, 8) | Analog power supply | Provides 3.0 V (2.7–3.6 V) for analog core and track-and-hold; decoupling near each pin essential for noise-sensitive sampling. |
| AIN / AIN (Pins 6, 7) | Differential analog input pair | Supports true differential or single-ended operation; internally biased at 0.3 × VD; input resistance ≈10 kΩ, capacitance = 2 pF. |
| ENCODE (Pin 10) | Sampling clock input | TTL/CMOS-compatible rising-edge trigger; timing jitter directly degrades SNR - requires low-phase-noise clock source. |
| D7–D0 (Pins 11–14, 17–20) | Parallel digital outputs | Offset binary coded, latched data with 2–3 ns output valid time; driven by separate VDD (Pin 15) for 2.5 V or 3.3 V logic compatibility. |
| VDD (Pin 15) | Digital output power supply | Independent 2.5–3.6 V rail isolates digital switching noise from analog section; enables mixed-voltage system interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold | Eliminates need for external THA, reducing BOM count and board area while maintaining 475 MHz analog bandwidth. |
| Integrated 1.25 V reference | Removes external reference IC and trimming components; ±130 ppm/°C tempco ensures stable full-scale over industrial temperature range. |
| No missing codes guaranteed | Ensures monotonic transfer function across full operating range - critical for control-loop feedback and waveform fidelity applications. |
| Separate digital output supply (VDD) | Allows seamless interfacing with 2.5 V or 3.3 V logic families without level shifters, simplifying FPGA/microcontroller integration. |
| Low-power power-down mode | Reduces total consumption to 4.2 mW and places outputs in high-Z state - enables rapid wake-up (<15 clocks) for burst-mode acquisition. |

FAQ
What is the operating temperature range for the AD9283BRS-RL50?
The AD9283BRS-RL50 is specified for the industrial temperature range of –40°C to +85°C. This rating is validated across all key parameters including SNR, DNL, INL, and power consumption. The device uses an advanced CMOS process and SSOP-20 packaging to ensure stability across this full range, making AD9283BRS-RL50 suitable for deployment in uncontrolled environments such as field test equipment and factory-floor monitors.
Does the AD9283BRS-RL50 require an external reference voltage?
No, the AD9283BRS-RL50 includes an on-chip 1.25 V reference (VREF OUT) that can be used directly by connecting Pin 2 (VREF OUT) to Pin 3 (VREF IN). When using the internal reference, the full-scale input range is 1.024 Vp-p, and performance remains fully specified. External references are optional for applications requiring tighter tolerance or different scaling - but AD9283BRS-RL50 needs no external reference to operate at datasheet performance.
How does the power-down mode function on the AD9283BRS-RL50?
The AD9283BRS-RL50 enters power-down mode when a logic HIGH is applied to Pin 1 (PWRDWN). Within two encode clock cycles, analog and digital circuitry shut down, reducing total power to 4.2 mW. Crucially, all eight digital outputs (D7–D0) transition to high-impedance state, eliminating bus contention. Recovery to full performance takes approximately 15 clock cycles after PWRDWN returns LOW - a feature leveraged in burst-mode acquisition systems using AD9283BRS-RL50.
What logic family is compatible with the digital outputs of the AD9283BRS-RL50?
The AD9283BRS-RL50 digital outputs are TTL/CMOS compatible and driven by a dedicated VDD pin (Pin 15) that accepts 2.5 V to 3.6 V. With VDD = 3.3 V, outputs swing from 0.05 V (logic LOW) to 2.95 V (logic HIGH); with VDD = 2.5 V, they remain compatible with 2.5 V logic families. This flexibility allows direct connection to FPGAs, microcontrollers, and ASICs without level-shifting circuitry - a key advantage confirmed in AD9283BRS-RL50's functional block diagram and timing specifications.
Is the AD9283BRS-RL50 pin-compatible with other members of the AD9283 family?
Yes, all AD9283 variants - including AD9283BRS-50, AD9283BRS-80, and AD9283BRS-100 - share identical SSOP-20 (RS-20) pinouts and footprint. The only differences are maximum sampling rate (50/80/100 MSPS), corresponding dynamic performance (e.g., SNR degradation above rated rate), and power consumption. Therefore, AD9283BRS-RL50 can be used in the same PCB layout as higher-speed variants, enabling scalable design reuse - a capability explicitly supported by Analog Devices' ordering guide and pin configuration documentation for AD9283BRS-RL50.
