MAX128BCNG+

ADCs/DACs - Special Purpose Overview

The MAX128BCNG+ is a monolithic sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features a 12-bit resolution and operates with a single +5V power supply. The device integrates an on-chip sample-and-hold amplifier and a high-speed conversion engine, achieving a throughput rate of 8k samples per second. Data transfer to the host system occurs via a standard serial interface compatible with SPI and QSPI protocols. The component is housed in a 28-pin narrow plastic small-outline package (NS-28) and is rated for operation within a commercial temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'BCNG+' against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices or lifecycle changes directly from Analog Devices, as availability may be restricted.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a moderate-speed, low-power 12-bit ADC is required for single-supply applications. Ensure the system clock requirements align with the internal timing. Compare against the MAX127 series if parallel interface options are preferred instead of serial communication.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX127/MAX128 family of 12-bit sampling ADCs. The MAX128 variant specifically provides a serial output interface, distinguishing it from parallel-output counterparts. It serves as a cost-effective solution for applications requiring precise analog-to-digital conversion without complex external interfacing logic.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX127BCNG+ offers identical performance but utilizes a parallel interface rather than serial. Verify pin compatibility before substitution. Other family members like the MAX129 provide higher speeds but may require different power management strategies.
