AD9051BRSZ

Overview

The AD9051BRSZ is a 10-bit, 60 MSPS monolithic sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features an onboard track-and-hold circuit and voltage reference, operating on a single 5 V supply with total power dissipation of 250 mW at maximum speed. The device utilizes a two-step subranging architecture to achieve high dynamic performance, delivering 9.3 effective number of bits (ENOB) at an input frequency of 10.3 MHz. It supports selectable input bandwidths of 50 MHz or 130 MHz via the BWSEL pin and offers 5 V or 3 V logic I/O compatibility. Packaged in a 28-lead SSOP, it operates within an industrial temperature range of –40 °C to +85 °C.

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific ordering suffix matches the required package variant and RoHS compliance status. Check current production status as legacy components may have limited availability. Ensure proper electrostatic discharge precautions are observed during handling due to device sensitivity.

Selection Notes

Select the AD9051BRSZ when a 10-bit resolution and 60 MSPS sampling rate are required for cost-sensitive applications. Choose this model if single-supply operation and onboard reference integration simplify the design. Consider the BRSZ variant for lead-free manufacturing requirements. Evaluate the need for external versus internal reference accuracy based on specific gain control requirements.

Part Context

The AD9051 belongs to the AD9051 series of high-speed data converters from Analog Devices. It is part of a family designed for low-cost, high-performance applications requiring moderate resolution and speed. The device shares architectural similarities with other members of the series but is distinct in its 10-bit resolution and specific power characteristics compared to higher or lower resolution variants.

Replacement Considerations

Direct replacements include the AD9051BRS (non-RoHS), AD9051BRSRL (reel packaging), and AD9051BRSZRL (RoHS reel). For dual-channel requirements, consider the AD9059 series. Verify pinout compatibility and electrical specifications before substituting with other manufacturers' parts.
