MAX192BCWP+T

ADCs/DACs - Special Purpose Overview

The MAX192BCWP+T is a low-cost, 10-bit data-acquisition system combining an 8-channel multiplexer, high-bandwidth track/hold, and serial interface. It operates on a single +5V supply with ultra-low power consumption of 1.5mA during operation and under 10µA in power-down modes. The device features an internal 4.096V reference with ±30ppm/°C drift and supports sampling rates up to 133ksps. It utilizes a 4-wire serial interface compatible with SPI, QSPI, Microwire, and TMS320 DSPs. The BC suffix indicates a ±1 LSB relative accuracy grade, housed in a 20-pin Wide SO package for the commercial temperature range.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type (Wide SOIC) and accuracy grade (B). Ensure compatibility with existing PCB footprints for the 20-pin SO package. Confirm that the commercial temperature range meets the operational requirements of the target environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a low-power, multi-channel ADC is required with direct microprocessor interface capabilities. The internal clock mode simplifies design by removing the need for an external conversion clock source. Consider the ±1 LSB accuracy specification for applications requiring moderate precision without external calibration.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX192 family of low-power, 8-channel, serial 10-bit ADCs. The 'B' designation specifies the accuracy grade, while 'WP' denotes the 20-pin Wide Small Outline Package. It serves as a pin-compatible upgrade path from the MAX186/MAX188 series, offering higher channel counts and lower power consumption.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192ACWP+T offers identical functionality with a different accuracy grade (±0.5 LSB INL/DNL vs ±1 LSB). For through-hole implementations, the MAX192BCPP+T provides the same electrical characteristics in a 20-pin Plastic DIP package.
