The MAX1492CAI+ from Analog Devices / Maxim Integrated is a versatile 3.5-digit analog-to-digital converter (ADC) designed for applications requiring precise measurement and display. It features an integrated triplexed LCD driver, simplifying system design by eliminating the need for external components like integrating capacitors, autozero capacitors, and crystal oscillators typically found in dual-slope ADCs.
This device operates from a single 2.7V to 5.25V supply and offers a selectable input range of ±200mV or ±2V. Communication with microcontrollers is facilitated via an SPI™, QSPI™, or MICROWIRE-compatible serial interface. The MAX1492CAI+ boasts high accuracy with continuous internal-offset calibration and provides over 100dB of simultaneous 50Hz and 60Hz line noise rejection. It also includes features such as data hold, peak hold, overrange and underrange detection, and a low-battery monitor.
Packaged in a 28-pin SSOP, the MAX1492CAI+ is suitable for surface mounting. It operates within a commercial temperature range of 0°C to +70°C, making it ideal for digital panel meters, hand-held meters, digital voltmeters, and digital multimeters.
Key specifications include a 3.5-digit resolution (±1999 count), a Sigma-Delta ADC architecture, and low power consumption with a maximum operating current of 960µA.
