Replacement verdict
Not a drop-in replacement
The AD9200ARSZRL and AD9201ARSRL are not drop-in replacements for one another. Although both are 10-bit CMOS analog-to-digital converters from Analog Devices in a 28-lead SSOP package, they differ in channel architecture, sampling rate, and supply configuration, so the AD9201ARSRL cannot be substituted directly into a design laid out for the AD9200ARSZRL without schematic and layout changes.

Key electrical and mechanical differences between the two devices
| Parameter | AD9200ARSZRL | AD9201ARSRL | Why it matters |
|---|---|---|---|
| Number of A/D Converters | 1 | 2 | The AD9201 integrates two ADCs in one package, enabling simultaneous I/Q or dual-channel sampling, while the AD9200 is a single-channel device. |
| Resolution | 10 bit | 10 bit | Both provide 10-bit resolution, so quantization accuracy is equivalent for each channel. |
| Sampling Rate | 20 MSPS | 20 MSPS | Identical maximum conversion rate means both can handle the same input signal bandwidth per channel. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Matching supply ranges allow either part to operate from the same power rail in a given design. |
| Package / Case | 28-SSOP | 28-SSOP | Same package and pin count simplify board-level substitution and layout reuse. |
| Input Type | Differential, Single-Ended | Differential, Single-Ended | Both support the same input configurations, so analog front-end design can remain unchanged. |
| Power Consumption | Approx. 100 mW | Approx. 200 mW | The dual-channel AD9201 dissipates roughly twice the power, which affects thermal and power budget planning. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical industrial temperature ratings ensure both parts suit the same environmental conditions. |

Frequently asked questions
What are the key differences between the AD9200ARSZRL and the AD9201ARSRL?
The AD9200ARSZRL is a single 10-bit, 20 MSPS analog-to-digital converter, while the AD9201ARSRL is a dual 10-bit, 20 MSPS ADC. The AD9200 integrates one ADC channel with an on-chip reference and sample-and-hold, whereas the AD9201 integrates two matched ADC channels in a single package for I/Q or dual-channel sampling applications. Both are offered in 28-lead SSOP packages and operate from a single supply, but the AD9201 provides two converters per device.
Are the AD9200ARSZRL and AD9201ARSRL pin-compatible or directly interchangeable?
No. Although both devices are housed in 28-lead SSOP packages, they are not pin-compatible because the AD9201 contains two ADC channels and therefore has different pin functions and signal assignments. The AD9200ARSZRL and AD9201ARSRL cannot be substituted directly without verifying pinout, supply, and interface differences against the respective manufacturer datasheets.
What are the resolution and sampling rate specifications of these two converters?
Both the AD9200ARSZRL and the AD9201ARSRL are 10-bit ADCs with a maximum sampling rate of 20 MSPS. The AD9200 provides a single 10-bit conversion channel, while the AD9201 provides two independent 10-bit conversion channels, each capable of 20 MSPS operation.
What supply voltage and power consumption do the AD9200ARSZRL and AD9201ARSRL require?
Both devices operate from a single 3 V supply (nominally 3.0 V, with the analog and digital supplies specified in the datasheets). The AD9200ARSZRL typically consumes approximately 100 mW at 3 V and 20 MSPS. The AD9201ARSRL, containing two ADC channels, typically consumes approximately 200 mW at 3 V and 20 MSPS. Designers should confirm exact supply ranges and power figures in the respective manufacturer datasheets.
Which applications favor the AD9201ARSRL over the AD9200ARSZRL?
The AD9201ARSRL is preferred in applications requiring two matched ADC channels in a compact footprint, such as I/Q demodulation, dual-channel baseband sampling, and communications receivers where channel-to-channel matching is important. The AD9200ARSZRL is suited to single-channel digitization tasks where one 10-bit, 20 MSPS converter is sufficient, offering a simpler single-channel signal path.
Do both parts support the same digital output interface and clock input?
Both devices provide parallel CMOS-compatible digital output buses and accept an external sampling clock. However, because the AD9201ARSRL contains two converters, it presents two output data buses and associated clocking for the dual channels, whereas the AD9200ARSZRL provides a single output bus. The exact output format, timing, and clock requirements must be verified in each device's datasheet before designing a shared interface.
What package and operating temperature range do the AD9200ARSZRL and AD9201ARSRL share?
Both devices are supplied in 28-lead SSOP (Shrink Small Outline Package) and are specified for the industrial temperature range of -40°C to +85°C. The "Z" suffix in AD9200ARSZRL denotes RoHS-compliant packaging, and designers should confirm the compliance status of the AD9201ARSRL against the manufacturer's ordering guide.
