MAX5105EEP+

Digital To Analog Converters Overview

The MAX5105EEP+ is a nonvolatile, quad, 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices / Maxim Integrated. It operates from a single +2.7V to +5.5V supply and features an internal EEPROM that stores DAC states for power-on reset initialization. The device includes four independent DAC channels with rail-to-rail output buffers, a software-controlled 10µA shutdown mode, and a mute state. It utilizes an SPI/QSPI/MICROWIRE-compatible serial interface. The MAX5105 variant includes an asynchronous MUTE input and an RDY/BSY status pin. It is housed in a 20-pin QSOP package and supports an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Internal EEPROM retains DAC and operating states after power removal for automatic initialization.
• Quad 8-bit DACs with independent high and low reference inputs and rail-to-rail output buffers.
• Low power consumption with 1mA typical supply current and 10µA maximum shutdown current.
• Asynchronous MUTE input and RDY/BSY pin for memory status indication (MAX5105 only).

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix corresponds to the required package type, as the MAX5105 is available in both 20-pin QSOP and 20-pin SO packages. Ensure compatibility with system voltage requirements ranging from +2.7V to +5.5V before procurement.

Digital To Analog Converters Selection Notes

Select the MAX5105EEP+ when nonvolatile storage of DAC settings is required to maintain state across power cycles. Choose this part over the MAX5106 if an asynchronous hardware MUTE input and a ready/busy status pin are necessary for system control. Verify that the 20-pin QSOP package fits the PCB layout constraints.

Digital To Analog Converters Part Context

The MAX5105EEP+ belongs to the MAX5105/MAX5106 family of nonvolatile quad DACs. It is functionally similar to the MAX5106 but adds specific control pins for system integration. The 'EEP+' suffix indicates the 20-pin QSOP package variant with lead-free construction and compliance with RoHS standards.

Digital To Analog Converters Replacement Considerations

The MAX5105EWP is a pin-compatible replacement offering the same electrical characteristics in a 20-pin wide SO package. No other direct substitutes are documented in the provided datasheet.
