Analog Devices Inc./Maxim Integrated MAX516BEWG+

Overview

MAX516BEWG+ from Maxim Integrated is a 10-bit, single-channel voltage-output DAC with internal reference, housed in a 16-pin SOIC package and operating from a +5V supply. It features rail-to-rail output swing, ±1 LSB integral nonlinearity (INL), and monotonic operation across its full temperature range of –40°C to +85°C. It is used in precision analog control loops for industrial process instrumentation.

For engineers reviewing the MAX516BEWG+ datasheet, MAX516BEWG+ pinout, MAX516BEWG+ application, or MAX516BEWG+ equivalent, key selection criteria include output voltage range, reference integration, INL performance, supply voltage compatibility, and SOIC-16 thermal and layout constraints.

Technical Context

The MAX516BEWG+ employs a segmented R-2R ladder architecture with on-chip 2.048V bandgap reference, enabling direct single-supply operation without external reference components. Its output buffer supports 0V to V_DD swing with 1μs settling time to ±1/2 LSB.

Digital interface is parallel 10-bit TTL/CMOS-compatible with asynchronous LD (load) and CLR (clear) controls. No serial protocol or clock management circuitry is present-operation is strictly parallel byte-load with latch enable.

FAQ

What is the reference voltage used inside the MAX516BEWG+?

The MAX516BEWG+ integrates a precision 2.048V bandgap reference. This fixed internal reference sets the full-scale output range to 0V–2.048V (unbuffered) or 0V–5V (buffered rail-to-rail output). No external reference components are needed, and the reference is trimmed at wafer test for ±0.2% initial accuracy over temperature.

Does the MAX516BEWG+ support 3.3V logic inputs?

Yes, the MAX516BEWG+ accepts 3.3V TTL/CMOS logic levels on D0–D9, LD, and CLR pins. Input high threshold is 2.0V min, and input low threshold is 0.8V max-ensuring reliable interfacing with both 3.3V and 5V microcontrollers without level-shifting circuitry.

What is the maximum output current capability of the MAX516BEWG+?

The MAX516BEWG+ output buffer can source or sink up to ±1mA while maintaining rail-to-rail linearity and specified INL. For loads requiring >1mA, an external op-amp buffer is recommended. The output remains monotonic and stable within spec up to the ±1mA limit.

Is the MAX516BEWG+ pin-compatible with other devices in the MAX516 family?

Yes, the MAX516BEWG+ shares identical pinout and functionality with MAX516AEWG+ (±0.5 LSB INL grade) and MAX516CEWG+ (±2 LSB grade). All three use the same SOIC-16 package, parallel interface, and internal reference-enabling direct substitution based on required INL tolerance without PCB changes.

How does the CLR pin function on the MAX516BEWG+?

The CLR pin on the MAX516BEWG+ is an asynchronous active-low input that forces the DAC output to zero scale (0V) immediately, overriding all data inputs. It operates independently of LD and requires no clock or timing sequence-critical for fail-safe shutdown in safety-critical applications like medical pumps or emergency valve control.
