MAX5101AEUE+

Digital To Analog Converters Overview

The MAX5101AEUE+ is a triple, parallel-input, voltage-output, 8-bit digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates on a single +2.7V to +5.5V supply and features internal precision buffers that swing rail-to-rail. The device includes three independent DACs with separate input latches, allowing data transfer from a common 8-bit port via address inputs A0 and A1. Key electrical characteristics include a typical supply current of 280µA, a shutdown current of 13µA, and an output settling time of 6µs. It is housed in a 16-pin TSSOP package.

Digital To Analog Converters Feature Summary

• Triple 8-bit DACs with individual input latches and rail-to-rail buffered outputs
• +2.7V to +5.5V single-supply operation with internal reference tied to VDD
• Ultra-low power consumption: 280µA operating current and 13µA shutdown current
• Power-on reset sets all registers to code 00 hex upon power-up

Digital To Analog Converters Applications

• Digital gain and offset adjustment
• Programmable attenuators
• Portable instruments
• Power-amp bias control

Digital To Analog Converters Procurement Notes

Verify the component authenticity by checking for the Maxim Integrated or Analog Devices branding on the 16-pin TSSOP package. Confirm the marking corresponds to the MAX5101AEUE variant, which specifies the -40°C to +85°C temperature range. Ensure the datasheet revision matches the provided documentation to validate electrical parameters such as INL/DNL and settling times.

Digital To Analog Converters Selection Notes

Select the MAX5101AEUE+ when a low-power, triple-channel DAC solution is required for portable applications. The 'E' suffix indicates the extended industrial temperature range (-40°C to +85°C), suitable for environments where standard commercial grades may fail. The parallel interface requires careful timing management for the WR pulse width and setup/hold times to ensure accurate data latching.

Digital To Analog Converters Part Context

The MAX5101 belongs to the Maxim Integrated family of low-power, multi-channel DACs designed for space-constrained systems. It utilizes a matrix decoding architecture with a resistor string tied to VDD, ensuring monotonic output without external components. This design simplifies board layout by eliminating the need for external reference voltages or buffer amplifiers.

Digital To Analog Converters Replacement Considerations

The MAX5101BEUE is a compatible alternative within the same series, offering identical functionality but with a guaranteed differential nonlinearity (DNL) of ±2 LSB compared to the AEUE's ±1 LSB. Both share the same pinout and electrical specifications except for linearity guarantees.
