Maxim Integrated Products introduced its MAX1336*/MAX1337 (8 bit), MAX1334*/MAX1335 (10bit), and max1332*/max1333 (12bit) family of high-speed, analog-to-digital converters (ADCs). These new ADCs feature two true-differential inputs, 3V or 5V single-supply operation, and a SPI-/QSPI-/microwire-compatible interface. Maxim added that its small, 9mm² footprint saves 85 percent board space and the low 67mW power dissipation consumes 40 percent less power than the closest competitor.

The ADCs all operate from either a 4.75V to 5.25V, or 2.7V to 3.6V single supply. The MAX1336/MAX1337 have a 6.5Msps (max) sampling rate, the MAX1334/MAX1335 have a 4.5Msps sampling rate, and the MAX1332/MAX1333 devices have a 4Msps (max) sampling rate. These products consume 12mA at the maximum conversion rate, and feature partial and full power-down modes that reduce the supply current to 3.3mA and 0.2µA, respectively. A separate DVDD pin allows direct interfacing to 1.8V to 3.6V digital logic.

With a high conversion rate and DC accuracy (±1LSB INL), these ICs are suitable for applications ranging from industrial process control and motor control to battery-powered wireless applications.

The MAX1336/MAX1337, MAX1334/MAX1335 and MAX1332/MAX1333 are available in a space-saving, 9mm², 16-pin TQFN package in the extended (-40°C to 85°C) temperature range. Prices start at $1.85 (1,000-up, FOB USA).
