MAX1245BCPP+

Analog To Digital Converters (ADC) Overview

The MAX1245BCPP+ is a 12-bit analog-to-digital converter (ADC) featuring an 8-channel multiplexer and a serial interface. It operates from a single +2.375V to +3.3V supply, with software-configurable unipolar or bipolar input ranges. The device integrates a high-bandwidth track/hold circuit and supports sampling rates up to 100ksps using either an internal clock or an external serial-interface clock. It provides a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The component is housed in a 20-pin Plastic DIP package and is rated for operation within a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel analog multiplexer with a high-bandwidth track/hold circuit for efficient multi-point data acquisition.
• Features a flexible 4-wire serial interface that connects directly to standard microprocessor communication protocols without requiring external logic gates.
• Supports ultra-low power consumption through a hardware-shutdown pin and software-selectable power-down modes, reducing current draw significantly during idle periods.

Analog To Digital Converters (ADC) Applications

• Portable Data Logging Systems
• Medical Instruments
• Battery-Powered Instruments
• Data Acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix PP+ indicates the 20-pin Plastic DIP package configuration when sourcing replacements. Confirm the BCPP variant meets the required integral nonlinearity specifications for your application. Ensure the operating environment remains within the specified commercial temperature limits. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-power, serially interfaced ADC is required for battery-operated devices. The BC grade offers tighter accuracy specifications compared to the AC grade. Consider the SSOP package option if board space is limited, as it occupies less area than the DIP version. Ensure the system voltage aligns with the single-supply requirement for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1245 family of low-power, serial 12-bit ADCs manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants with different accuracy grades and temperature ranges. The BCPP+ designation specifically identifies the commercial temperature range version with improved linearity specifications packaged in a standard dual in-line format.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives include other members of the MAX1245 series such as the MAX1245ACPP+ or MAX1245AEPP+. Verify that substitute parts match the required accuracy grade and operating temperature range before implementation.
