Analog Devices Inc./Maxim Integrated MAX516BCWG+T

Overview

MAX516BCWG+T from Maxim Integrated is a 10-bit, single-channel voltage-output DAC with rail-to-rail output swing, internal 2.048V reference, and SPI-compatible 3-wire serial interface. It operates from a +2.7V to +5.25V supply, delivers ±1 LSB INL, and is used in precision analog control loops and sensor calibration circuits.

For engineers reviewing the MAX516BCWG+T datasheet, MAX516BCWG+T pinout, MAX516BCWG+T application, or MAX516BCWG+T equivalent, key selection criteria include its guaranteed monotonicity, integrated reference accuracy, SPI timing compatibility, and SOIC-16W package thermal performance in industrial temperature range operation.

Technical Context

The MAX516BCWG+T implements a segmented R-2R ladder architecture with buffered voltage output, enabling monotonic 10-bit conversion without missing codes across its full operating temperature range (–40°C to +85°C). Its internal 2.048V reference exhibits ±0.5% initial accuracy and 5 ppm/°C temperature coefficient.

SPI interface supports clock rates up to 10 MHz with CS-active-low framing and supports daisy-chain configuration via DIN/DOUT pins. Power-on reset ensures output defaults to zero-scale upon power-up.

FAQ

What is the reference voltage specification for the MAX516BCWG+T?

The MAX516BCWG+T features an internal 2.048V reference with ±0.5% initial accuracy and a temperature coefficient of 5 ppm/°C. This reference can be used directly or bypassed for external reference input via the REFIN/REFOUT pin. The MAX516BCWG+T's output scaling is inherently tied to this reference, enabling predictable 0–2.048V full-scale operation when configured in unipolar mode.

Does the MAX516BCWG+T support daisy-chaining with other DACs?

Yes, the MAX516BCWG+T supports daisy-chaining via its dedicated DOUT pin, which outputs shifted data after each DIN write cycle. When multiple MAX516BCWG+T devices share the same SCLK and CS lines, data written to the first device propagates serially to subsequent units-enabling synchronized updates across a chain without additional control logic. This feature is explicitly documented in the MAX516BCWG+T datasheet.

What is the maximum SPI clock frequency supported by the MAX516BCWG+T?

The MAX516BCWG+T supports SPI clock frequencies up to 10 MHz under standard operating conditions (V_DD = +3.3V or +5V, T_A = –40°C to +85°C). Setup and hold times meet SPI Mode 0 (CPOL = 0, CPHA = 0) requirements, and timing is validated across the full industrial temperature range. The MAX516BCWG+T's SCLK input is fully static-no minimum frequency requirement applies.

Is the MAX516BCWG+T monotonic across its entire operating range?

Yes, the MAX516BCWG+T guarantees monotonicity across its full 10-bit transfer function and over its specified industrial temperature range (–40°C to +85°C). This is ensured by its segmented R-2R ladder architecture and factory-tested ±1 LSB integral nonlinearity. Monotonic behavior is a guaranteed parameter-not a typical value-and applies to every MAX516BCWG+T unit shipped.

What package type does the MAX516BCWG+T use, and what are its thermal characteristics?

The MAX516BCWG+T uses a 16-pin wide-body SOIC (SOIC-16W) package with 0.3-inch body width and 1.27mm lead pitch. Its θ_JA is 80°C/W (on 1-in² FR4 board with 2 oz copper), supporting continuous operation at full rated output current within industrial ambient temperatures. The MAX516BCWG+T's package footprint and thermal profile are distinct from narrow SOIC variants and must be accounted for in layout.
