MAX196BCAI

ADCs/DACs - Special Purpose Overview

The MAX196BCAI is a 12-bit, 100ksps data-acquisition system (DAS) in a 28-pin SSOP package. It integrates a 6-channel analog multiplexer, track/hold amplifier, and successive approximation register ADC. Operating on a single +5V supply, it supports software-selectable input ranges including ±10V, ±5V, 0V to +10V, and 0V to +5V. The device features fault-protected inputs rated to ±16.5V, a 12-bit parallel interface, and internal or external clock options. Electrical specifications include ±1 LSB DNL, ±1/2 LSB INL, and a typical power dissipation of 762mW in the SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'BCAI' corresponds to the commercial temperature range (0°C to +70°C) and 28-SSOP package. Confirm RoHS compliance status for the '+' suffix variant if required by assembly standards. Check for obsolescence notices as this component originates from the Maxim Integrated era prior to full Analog Devices integration.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX196BCAI for applications requiring multirange input flexibility without external scaling amplifiers. Ensure the microprocessor interface timing matches the 12-bit parallel bus requirements. For higher channel counts, consider the MAX199 series; for serial interfaces, evaluate alternative ADC families.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX196/MAX198 family of multirange DAS devices. The 'B' grade indicates tighter linearity specifications compared to the 'A' grade. The 'CAI' suffix denotes the commercial temperature range and SSOP packaging. It serves as a direct predecessor to later integrated ADC solutions with simplified digital interfaces.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements are limited due to the specific 12-bit parallel interface and multirange architecture. Verify functional equivalence regarding input range scaling factors and timing parameters when considering cross-family alternatives.
