MAX186BEAP

ADCs/DACs - Special Purpose Overview

The MAX186BEAP+ is a 12-bit, low-power analog-to-digital converter (ADC) featuring an 8-channel multiplexer and a high-bandwidth track/hold circuit. It operates on a single +5V or dual ±5V supply with software-configurable unipolar/bipolar and single-ended/differential inputs. The device integrates a 4.096V reference and utilizes a 4-wire serial interface compatible with SPI, QSPI, and Microwire standards. Key electrical parameters include a 133ksps sampling rate, 1.5mA operating current, and 2µA power-down current. It is housed in a 20-pin SSOP package and supports an industrial temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'EAP+' corresponds to the -40°C to +85°C temperature grade and SSOP package. Confirm RoHS compliance status for the exact manufacturing lot. Check for availability of evaluation kits if hardware validation is required during the design phase.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 12-bit ADC with multiple channels and low power is needed. Ensure the system requires a single +5V or dual ±5V supply. Verify that the serial interface timing matches the host microcontroller's SPI or Microwire configuration. Consider the internal reference stability if external precision references are not available.

ADCs/DACs - Special Purpose Part Context

The MAX186BEAP+ belongs to the MAX186/MAX188 family of low-power, serial 12-bit ADCs. The MAX186 variant includes an internal reference, whereas the MAX188 requires an external one. This specific part number denotes the B-grade performance level within the industrial temperature range (-40°C to +85°C) packaged in a shrink small-outline package (SSOP).

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include other grades like MAX186CEAP+ (commercial grade) or MAX186AEAP+ (higher accuracy). Ensure the replacement maintains the same package type and temperature rating.
