MAX192BEPP

ADCs/DACs - Special Purpose Overview

The MAX192BEPP 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 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 specifications include a sampling rate of 133 kS/s, ±1 LSB integral nonlinearity (INL), and ±1 LSB differential nonlinearity (DNL). It operates within a temperature range of -40°C to +85°C and is housed in a 20-pin PDIP package.

ADCs/DACs - Special Purpose Feature Summary

• 8-channel multiplexer with software-selectable single-ended or differential input configurations
• Internal 4.096V reference with ±30ppm/°C drift and reference-buffer amplifier
• Low power consumption: 1.5mA operating current and under 10µA in full power-down mode
• Serial strobe output (SSTRB) for direct connection to TMS320 DSPs

ADCs/DACs - Special Purpose Applications

• Portable data logging systems
• Battery-powered instruments and battery management
• Medical instrumentation
• Robotics control systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) and 'PP' denotes the 20-pin plastic DIP package. Confirm RoHS compliance status as indicated by the '+' suffix in ordering information. Ensure the source document matches the manufacturer's official datasheet for accurate pinout and electrical limits.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192BEPP when an 8-channel acquisition system with 10-bit resolution and 133 kS/s throughput is required. Choose this part over the MAX192AEPP if the application demands ±1 LSB INL instead of ±0.5 LSB. Ensure the design accommodates the 20-pin PDIP footprint and +5V single-supply requirement.

ADCs/DACs - Special Purpose Part Context

The MAX192BEPP belongs to the MAX192 family of low-cost, serial ADCs. It serves as a pin-compatible upgrade path from the 8-bit MAX186/MAX188 series, allowing designers to increase resolution without changing the PCB layout. The 'B' grade specifies tighter linearity tolerances compared to the 'A' grade variants.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192AEPP is a pin-compatible alternative offering higher accuracy (±0.5 LSB INL) but requires verification of temperature range compatibility. Other MAX192 variants with different packages (SO, SSOP) are electrically similar but require footprint changes.
