Replacement verdict
Compatible functional replacement candidate
The AD9057BRS-60 is a viable functional replacement candidate for the AD9059BRS in many designs, as both are 8-bit analog-to-digital converters sharing a compatible package footprint and supply architecture. However, the AD9057BRS-60 offers a higher maximum sampling rate while the AD9059BRS provides dual internal track-and-hold channels, so designers must validate the specific sampling-rate and channel-count requirements of their application before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | AD9059BRS | AD9057BRS-60 | Why it matters |
|---|---|---|---|
| Resolution | 8 bit | 8 bit | Both converters provide 8-bit resolution, so quantization granularity is equivalent for signal reconstruction. |
| Sampling Rate | 60 MSPS | 60 MSPS | Identical maximum sampling rate means both can digitize signals up to the same Nyquist bandwidth. |
| Number of Input Channels | 2 (dual) | 1 (single) | A dual-channel device can sample two signals simultaneously, while a single-channel part requires external multiplexing for multi-signal systems. |
| Analog Input Type | Single-ended | Single-ended | Both accept single-ended inputs, simplifying the analog front-end drive requirements. |
| Supply Voltage | 5 V | 5 V | Matching 5 V supply allows the parts to share the same power rail in a system design. |
| Output Interface | Parallel CMOS/TTL | Parallel CMOS/TTL | Identical parallel output format enables direct connection to the same digital backend without glue logic changes. |
| Package | 28-lead SSOP | 20-lead SSOP | Different package footprints and pin counts prevent drop-in board replacement without layout changes. |
| Power Consumption | ~400 mW (typ) | ~300 mW (typ) | Lower power dissipation affects thermal design and supply sizing, especially in dense or portable systems. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Equivalent industrial temperature range means both suit the same environmental conditions. |

Frequently asked questions
What are the key differences between the AD9059BRS and AD9057BRS-60?
The AD9059BRS is a dual 8-bit analog-to-digital converter, while the AD9057BRS-60 is a single 8-bit ADC. The AD9057BRS-60 is specified for a 60 MSPS sampling rate, whereas the AD9059BRS is a dual-channel device intended for applications requiring two synchronized 8-bit conversion channels. Pin count, channel architecture, and power consumption differ between the two devices, so they are not drop-in replacements.
Are the AD9059BRS and AD9057BRS-60 pin-compatible?
No. The AD9059BRS is a dual-channel ADC and the AD9057BRS-60 is a single-channel ADC, so their pinouts and package pin functions differ. A direct PCB substitution is not possible without layout changes.
What is the resolution and sampling rate of each device?
Both devices provide 8-bit resolution. The AD9057BRS-60 is specified for a 60 MSPS maximum sampling rate. The AD9059BRS is a dual 8-bit ADC; its sampling rate specification should be confirmed from the Analog Devices datasheet for the exact grade, as it differs from the single-channel AD9057BRS-60.
Can the AD9057BRS-60 replace one channel of the AD9059BRS?
Functionally, the AD9057BRS-60 provides a single 8-bit conversion channel, so two AD9057BRS-60 devices could in principle serve a dual-channel function. However, this requires two packages, separate clock and layout considerations, and validation of timing and power against the original AD9059BRS design. It is not a direct one-for-one replacement.
Do both parts use the same package type?
Both are offered in surface-mount packages, but the specific package and pin count differ because the AD9059BRS is dual-channel and the AD9057BRS-60 is single-channel. Package and land pattern compatibility must be verified from the respective Analog Devices datasheets before any substitution.
Which device should be selected for a dual-channel acquisition design?
The AD9059BRS is the appropriate choice when two matched 8-bit conversion channels are required in a single package, since it integrates dual ADCs. The AD9057BRS-60 is a single-channel device and would require two instances for a dual-channel design, with additional board space and clock distribution considerations.
Are these parts still recommended for new designs?
Both the AD9059BRS and AD9057BRS-60 are legacy Analog Devices converter products. Designers should confirm current lifecycle status, availability, and any recommended replacement parts directly with Analog Devices or authorized distributors before committing to new designs.
