MAX192AEAP

ADCs/DACs - Special Purpose Overview

The MAX192AEAP is a low-power, 8-channel, serial 10-bit analog-to-digital converter (ADC) from the MAX192 family. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuit, and successive approximation register (SAR) architecture. The device operates on a single +5V supply with a sampling rate of 133 kS/s using an internal clock or external serial interface clock. It features a 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. The part is housed in a 20-pin shrink-small-outline package (SSOP) and supports an operating temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix 'AEAP' corresponds to the 20-pin SSOP package and the -40°C to +85°C industrial temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the source document explicitly lists this exact part number variant to avoid confusion with other package types like DIP or Wide SO.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192AEAP when an SSOP footprint is required for space-constrained designs within the industrial temperature range. This variant offers pin compatibility with the 12-bit MAX186/MAX188 for potential future upgrades. Consider the internal reference drift specifications if external precision references are not utilized in the application design.

ADCs/DACs - Special Purpose Part Context

The MAX192AEAP belongs to the MAX192 series of low-cost, low-power data-acquisition systems. It shares functional similarities with the MAX192ACAP but differs in its specified operating temperature range (-40°C to +85°C versus 0°C to +70°C). The 'E' suffix denotes the extended temperature grade, while 'A' indicates the specific linearity performance class defined in the datasheet.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192BEAP is a pin-compatible alternative within the same package offering different integral nonlinearity (INL) specifications. For higher resolution requirements, the MAX186 and MAX188 provide 12-bit performance with identical pinouts.
