MAX192BCPP

ADCs/DACs - Special Purpose Overview

The MAX192BCPP is a low-power, 8-channel, serial 10-bit analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuit, and a 4-wire serial interface compatible with SPI, QSPI, and Microwire standards. Operating on a single +5V supply, it features an internal 4.096V reference and supports both single-ended and differential input configurations. The device utilizes successive approximation architecture with a sampling rate of 133ksps. It offers flexible power management with two software-selectable power-down modes, reducing current to under 10µA. The component is housed in a 20-pin Plastic DIP package and operates within a temperature range of 0°C to +70°C.

• Medical instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CPP' corresponds to the 20-pin Plastic DIP package and the 'B' grade for ±1 LSB INL/DNL accuracy. Confirm the operating temperature range is 0°C to +70°C. Check RoHS compliance status as indicated by the '+' suffix if applicable. Ensure the source document matches the manufacturer's official datasheet for electrical characteristics.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192BCPP when a 10-bit resolution and 133ksps sampling rate are required for multi-channel acquisition. Choose this part over the 'A' grade variant if tighter linearity specifications (±1 LSB vs ±0.5 LSB) are acceptable for cost reduction. Ensure the application environment stays within the 0°C to +70°C commercial temperature range. Verify that the system can accommodate the 20-pin DIP footprint.

ADCs/DACs - Special Purpose Part Context

The MAX192BCPP belongs to the MAX192 family of low-power, serial ADCs. It is pin-compatible with the 12-bit MAX186 and MAX188, allowing for potential upgrades without PCB redesign. The 'B' suffix denotes a specific accuracy grade compared to the 'A' grade, while 'CPP' indicates the 20-pin Plastic DIP packaging. This component serves as a bridge between analog sensor signals and digital processing units in embedded systems.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192ACPP is a pin-compatible alternative with higher accuracy (±0.5 LSB INL) but may have different availability. For 12-bit resolution upgrades, consider the MAX186 or MAX188 which share the same pinout. No direct cross-model substitutes are confirmed in the provided documentation beyond these family members.
