Product details
Overview
AD9283BRSZ-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), 1 Vp-p analog input range, and 475 MHz analog bandwidth. 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 handheld scopemeters.
For engineers reviewing the AD9283BRSZ-RL50 datasheet, AD9283BRSZ-RL50 pinout, AD9283BRSZ-RL50 application, or AD9283BRSZ-RL50 equivalent, key selection considerations include its 20-lead SSOP package, TTL/CMOS-compatible digital outputs, internal 1.25 V reference, single-ended or differential analog input capability, and guaranteed no-missing-codes performance across –40°C to +85°C.
Technical Context
The AD9283BRSZ-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 0 ns aperture delay, enabling accurate sampling up to 100 MSPS (though this variant is rated for 50 MSPS).
Digital outputs use offset binary coding and are driven from a dedicated VDD pin (2.5–3.6 V), allowing direct interfacing with 2.5 V or 3.3 V logic. The PWRDWN pin asserts high-impedance state on all D7–D0 outputs within two clock cycles, with full performance restored in ~15 encode cycles after exit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - fixed word length defining quantization step size and dynamic range |
| Sampling Rate | 50 MSPS - maximum sustained conversion rate with full DC and AC performance guaranteed |
| Analog Input Range | 1.024 Vp-p - full-scale differential input swing referenced to internal 1.25 V reference |
| SNR @ 41 MHz | 46.5 dB - signal-to-noise ratio limiting usable bandwidth in high-frequency digitization |
| Power Dissipation | 80 mW typical at 50 MSPS - enables thermal management in compact portable instruments |
| Power-Down Power | 4.2 mW - reduces system-level standby consumption without external component removal |

Pinout & Package
AD9283BRSZ-RL50 is housed in a 20-lead shrink small outline plastic package (SSOP, RS-20) with 0.65 mm lead pitch, specified for industrial temperature range (–40°C to +85°C). Thermal resistance θJA = 126°C/W enables passive cooling in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWRDWN (Pin 1) | Power-down control input | Logic HIGH forces digital outputs into high-impedance state and reduces total power to 4.2 mW |
| VREF OUT (Pin 2) | Internal reference output | Provides 1.25 V ±130 ppm/°C reference; requires 0.1 µF bypass capacitor to GND |
| VREF IN (Pin 3) | Reference input | Accepts external reference or connects to Pin 2 for internal reference use |
| GND (Pins 4, 9, 16) | Analog/digital ground | Three separate ground pins minimize noise coupling between analog and digital sections |
| VD (Pins 5, 8) | Analog power supply | 3.0 V ±0.3 V analog supply; dual pins reduce IR drop and improve PSRR |
| AIN / AIN (Pins 6, 7) | Differential analog inputs | Support single-ended or differential drive; internally biased at 0.3 × VD for flexible ac/dc coupling |
| ENCODE (Pin 10) | Sampling clock input | TTL/CMOS-compatible; rising-edge triggered; timing jitter directly degrades SNR |
| D7–D0 (Pins 11–14, 17–20) | Digital data outputs | Offset binary coded; driven from VDD (Pin 15); high-impedance during power-down |
| VDD (Pin 15) | Digital output supply | Independent 2.5–3.6 V supply enables level-shifting to match host logic voltage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, medium-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9280ARSZ | 10-bit resolution, 32 MSPS max, 3.3 V supply only, no on-chip reference | Higher resolution but lower speed and no internal reference - requires external REF and level-shifting for 3 V systems | Select when 10-bit precision outweighs speed and integration trade-offs |
| MAX1186EEE+ | 8-bit, 40 MSPS, 3 V supply, internal reference, but only 350 MHz analog bandwidth and 44 dB SNR @ 41 MHz | Lower analog bandwidth and SNR limit usability in wideband or high-fidelity applications | Select for cost-sensitive designs where 475 MHz bandwidth and 46.5 dB SNR are not required |
Compared with AD9283BRSZ-RL50, AD9280ARSZ trades speed and integration for resolution, while MAX1186EEE+ sacrifices bandwidth and SNR for lower cost - making AD9283BRSZ-RL50 optimal for portable instrumentation needing balanced speed, fidelity, and self-contained operation.

FAQ
What is the maximum analog input frequency supported by the AD9283BRSZ-RL50?
The AD9283BRSZ-RL50 features a 475 MHz analog bandwidth, meaning it can accurately digitize input signals with frequency content up to approximately 237.5 MHz (Nyquist limit at 50 MSPS). Measured SNR remains 46.5 dB at 41 MHz input, confirming robust high-frequency performance well within its specified operating range.
Does the AD9283BRSZ-RL50 require an external reference voltage?
No - the AD9283BRSZ-RL50 includes an on-chip 1.25 V reference (VREF OUT, Pin 2) with ±130 ppm/°C tempco. For standard operation, Pins 2 and 3 are strapped together to use the internal reference. An external reference may be applied to Pin 3 if tighter accuracy or adjustable full-scale range is needed, but it is not required.
How does the power-down mode affect the digital outputs of the AD9283BRSZ-RL50?
When PWRDWN (Pin 1) is asserted HIGH, the AD9283BRSZ-RL50 places all eight digital outputs (D7–D0) into a high-impedance state within two encode cycles, and total power drops to 4.2 mW. Outputs remain tri-stated until PWRDWN returns LOW, after which full performance resumes in approximately 15 encode cycles.
What is the purpose of the separate VDD pin (Pin 15) on the AD9283BRSZ-RL50?
Pin 15 (VDD) supplies power exclusively to the digital output buffers of the AD9283BRSZ-RL50, allowing independent voltage setting between 2.5 V and 3.6 V. This enables direct interface with 2.5 V or 3.3 V logic families without level shifters, while isolating digital switching noise from the analog supply (VD, Pins 5/8).
Is the AD9283BRSZ-RL50 compatible with single-ended analog input configurations?
Yes - the AD9283BRSZ-RL50 supports both differential and single-ended analog inputs. For single-ended use, one input (e.g., AIN, Pin 6) receives the signal while the other (AIN, Pin 7) is terminated to ground via a 0.1 µF capacitor and 25 Ω resistor, per Analog Devices' recommended layout for optimal matching and noise rejection.
