Key electrical and mechanical differences between the two devices
| Parameter | AD9280ARSZRL | AD9283BRS-RL100 | Why it matters |
|---|---|---|---|
| Resolution | 8 bits | 8 bits | Both are 8-bit ADCs, so quantization resolution is equivalent for substitutability. |
| Sampling Rate | 32 MSPS | 100 MSPS | The AD9283 supports a much higher conversion rate, enabling wider input bandwidth and faster signal capture. |
| Supply Voltage | 2.7 V to 5.5 V | 3.0 V (2.7 V to 3.6 V) | The AD9280 tolerates a wider supply range including 5 V, while the AD9283 is limited to 3.3 V-class rails. |
| Analog Input Range | 1 V p-p to 2 V p-p (programmable) | 1 V p-p | The AD9280 offers a programmable input span, allowing better matching to different signal amplitudes. |
| Power Consumption | ~95 mW at 32 MSPS | ~90 mW at 100 MSPS | Power budget affects thermal design and supply sizing; the AD9283 delivers higher speed at comparable power. |
| Package | 28-lead SSOP | 20-lead SSOP | Different footprints and pin counts mean the parts are not drop-in replacements on an existing PCB. |
| Output Interface | Parallel CMOS | Parallel CMOS | Both provide parallel CMOS outputs, simplifying digital interface compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical industrial temperature ratings support use in the same environmental conditions. |

Frequently asked questions
What are the key differences between the AD9280ARSZRL and AD9283BRS-RL100?
The AD9280ARSZRL is a 32 MSPS, 8-bit analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference, housed in a 28-lead SSOP. The AD9283BRS-RL100 is an 8-bit, 100 MSPS ADC in a 20-lead SSOP. The primary differences are sampling rate (32 MSPS vs 100 MSPS), package/pin count (28-lead vs 20-lead SSOP), and power consumption scaling with speed.
Are the AD9280ARSZRL and AD9283BRS-RL100 pin-compatible?
No. The AD9280ARSZRL uses a 28-lead SSOP package, while the AD9283BRS-RL100 uses a 20-lead SSOP package. The differing pin counts and pin functions mean they are not drop-in replacements and require different PCB footprints.
What are the maximum sampling rates of these two ADCs?
The AD9280ARSZRL has a maximum sampling rate of 32 MSPS. The AD9283BRS-RL100 has a maximum sampling rate of 100 MSPS, making it suitable for higher-bandwidth signal acquisition applications.
What is the resolution and input architecture of both converters?
Both devices are 8-bit ADCs. The AD9280ARSZRL integrates an on-chip sample-and-hold amplifier and a voltage reference, accepting a 1 V peak-to-peak input range. The AD9283BRS-RL100 is an 8-bit pipelined ADC with an on-chip sample-and-hold, designed for high-speed signal conversion.
How do the power consumption figures compare?
The AD9280ARSZRL typically dissipates about 95 mW at 32 MSPS from a single 3 V supply. The AD9283BRS-RL100 typically dissipates about 90 mW at 100 MSPS from a 3 V supply. Exact values should be confirmed against the respective manufacturer datasheets for the specific operating conditions.
Can the AD9283BRS-RL100 replace the AD9280ARSZRL in an existing design?
Not directly. Although both are 8-bit ADCs, the AD9283BRS-RL100 has a different package (20-lead vs 28-lead SSOP), different pinout, and a higher maximum sampling rate. A replacement requires PCB redesign, revalidation of the clock and input interface, and confirmation that the higher speed does not violate downstream timing.
What supply voltage do these ADCs require?
Both the AD9280ARSZRL and AD9283BRS-RL100 operate from a single 3 V supply (nominally 2.7 V to 3.6 V). Designers should verify the exact recommended operating range in the respective manufacturer datasheets.
