MAX192ACPP+

ADCs/DACs - Special Purpose Overview

The MAX192ACPP+ 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 successive-approximation register (SAR) architecture. Operating on a single +5V supply, it supports software-configurable single-ended and differential inputs. The device features a 4-wire serial interface compatible with SPI, QSPI, and Microwire standards. Key electrical parameters include a sampling rate of 133 kS/s, an internal 4.096V reference, and power consumption of 1.5mA in operating mode and under 10µA in full power-down mode.

• Robotics control systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the component designation MAX192ACPP+ against official Analog Devices documentation to confirm the specific package type (20-pin Plastic DIP) and temperature range (0°C to +70°C). Ensure that the ordering suffix corresponds to the required industrial specifications and RoHS compliance status as defined in the manufacturer's datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192ACPP+ for applications requiring low-cost, multi-channel data acquisition with minimal power draw. The device is suitable for systems needing 10-bit resolution at 133 kS/s. Consider the internal clock option for simplified microprocessor timing or external clock mode for precise synchronization. Verify that the source impedance of analog inputs remains below 5kΩ to maintain specified acquisition times without additional buffering.

ADCs/DACs - Special Purpose Part Context

The MAX192 belongs to the Maxim Integrated low-power ADC family, designed for cost-sensitive embedded applications. It offers pin compatibility with the 12-bit MAX186/MAX188 series, allowing for potential upgrade paths within the same footprint. The AC grade specifies commercial temperature operation, distinguishing it from the extended temperature BE and AE variants.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192AEPP+ serves as a direct replacement for extended temperature ranges (-40°C to +85°C). For higher resolution requirements, the MAX186 or MAX188 provide pin-compatible 12-bit upgrades. Ensure that any substitute maintains the 20-pin DIP package and +5V single-supply operation constraints.
