Replacement verdict
Not a drop-in replacement
The AD9059BRS and AD9051BRS-2V are both dual 8-bit analog-to-digital converters, but they differ in sampling rate, analog input bandwidth, package footprint, and power consumption, so the AD9051BRS-2V cannot be used as a direct drop-in substitute for the AD9059BRS without design validation.

Key electrical and mechanical differences between the two devices
| Parameter | AD9059BRS | AD9051BRS-2V | Why it matters |
|---|---|---|---|
| Resolution | 8 bit | 10 bit | Higher resolution provides finer quantization and better dynamic performance, so the two parts are not directly substitutable in precision-sensitive designs. |
| Sampling Rate | 60 MSPS | 60 MSPS | The maximum conversion rate determines the highest input signal bandwidth the ADC can digitize; matching rates allow similar throughput. |
| Number of Input Channels | 2 (dual) | 1 (single) | A dual-channel ADC can sample two signals simultaneously, while a single-channel part requires external multiplexing, affecting system architecture. |
| Supply Voltage | 5 V | 5 V | Supply voltage must match the surrounding analog and digital rails for proper operation and interface compatibility. |
| Analog Input Range | 1 V p-p | 2 V p-p | Input full-scale range affects the required driver amplifier swing and overall signal-to-noise performance. |
| Output Interface | Parallel CMOS | Parallel CMOS | The digital output format must be compatible with the downstream FPGA or DSP receiver logic. |
| Package | 28-Lead SSOP | 28-Lead SSOP | Package and pinout determine board footprint and whether a drop-in replacement is physically possible. |
| Power Consumption | ~400 mW | ~450 mW | Power dissipation impacts thermal design and supply sizing, especially in densely packed or battery-powered systems. |

Frequently asked questions
What are the key differences between the AD9059BRS and AD9051BRS-2V?
The AD9059BRS is a dual 8-bit, 60 MSPS analog-to-digital converter, while the AD9051BRS-2V is a single 10-bit, 60 MSPS ADC. The AD9059 provides two matched 8-bit channels in one package, whereas the AD9051 offers higher vertical resolution (10-bit) on a single channel. Both are housed in 28-lead SSOP packages and operate from a single 5 V supply.
Do the AD9059BRS and AD9051BRS-2V have the same pinout and package?
Both devices are offered in a 28-lead SSOP (RS) package, but their pinouts differ because the AD9059 is a dual-channel device and the AD9051 is single-channel. They are not pin-compatible drop-in replacements; the PCB layout and pin assignments must be verified against each respective datasheet before substitution.
What is the resolution and sampling rate of each converter?
The AD9059BRS provides 8-bit resolution per channel with a maximum sampling rate of 60 MSPS on two simultaneous channels. The AD9051BRS-2V provides 10-bit resolution with a maximum sampling rate of 60 MSPS on a single channel. The "-2V" suffix denotes the 2 V peak-to-peak input voltage range option for the AD9051.
What input voltage range does the AD9051BRS-2V support compared with the AD9059BRS?
The AD9051BRS-2V is specified with a 2 V peak-to-peak differential input span, as indicated by the "-2V" grade designation. The AD9059BRS uses a nominal 1 V peak-to-peak input range. Designers must scale the analog front-end drive accordingly when comparing or substituting these parts.
Are both devices suitable for the same applications?
Both are 60 MSPS CMOS ADCs suited to digitizing high-speed analog signals, but their channel count and resolution differ. The AD9059BRS fits applications requiring two matched 8-bit channels, such as I/Q baseband sampling. The AD9051BRS-2V fits single-channel applications needing 10-bit resolution, such as imaging or instrumentation front ends. Application suitability must be evaluated against each datasheet's specifications.
What supply voltage and output interface do these converters use?
Both the AD9059BRS and AD9051BRS-2V operate from a single 5 V analog and digital supply and provide CMOS-compatible digital output levels. The AD9059 outputs two 8-bit words, while the AD9051 outputs a single 10-bit word. Refer to the respective datasheets for exact timing and output loading specifications.
Can the AD9051BRS-2V directly replace the AD9059BRS on an existing board?
No. Although both use a 28-lead SSOP package, the AD9059BRS is a dual 8-bit converter and the AD9051BRS-2V is a single 10-bit converter with a different pinout and input range. A direct drop-in replacement is not possible; any substitution requires a redesign validated against both manufacturer datasheets.
