Maxim introduces the MAX1300-MAX1303 and MAX1032-MAX1035 family of 16-/14-bit ADCs. These devices have a ±12V input range. Integrated software lets the user remotely configure each input of equipment to a unique voltage range. Each input channel can be programmed with seven different input ranges for single-ended inputs and three different input ranges for differential inputs. The programmable analog input-voltage ranges are ±24V, ±12V, ±6V, ±3V, 0 to +12V, -12V to 0, 0 to +6V, and -6V to 0. This ADC family offers up to eight single-ended inputs or four differential inputs, all of which are ±16.5V overvoltage tolerant. The ADCs allow accurate measurement of temp sensors, Wheatstone bridges, pressure sensors, PLC, 4mA to 20mA loop under normal operating conditions, and overvoltage conditions utilizing the ±12V analog input-voltage range. AC performance (THD of -97dB, typ) and DC accuracy (±2 LSB INL, max) make the devices dedicated for industrial process control, instrumentation, and data acquisition systems.
The MAX1300-MAX1303 and MAX1032-MAX1035 operate from a single +5V supply and feature a separate DVDD pin, which allows direct interfacing to +2.7V to +5.25V digital logic. An internal or external 4.096V reference determines the full-scale analog-input range. Packaging varies by the parts. The 16-bit, 8-channel ADCs with a ±12V/±VREF input range (MAX1300*/MAX1302*) are available in a 24-pin TSSOP, while the 16-bit, 4-channel devices with a ±12V/±VREF input range (MAX1301/MAX1303) are available in a 20-pin TSSOP. The 14-bit, 8-channel ADCs with a ±12V/±VREF input range (MAX1032*/MAX1034*) are available in a 24-pin TSSOP, and the 14-bit, 4-channel parts with a ±12V/±VREF input range (MAX1033/MAX1035) are available in a 20-pin TSSOP. Prices for these ADCs start at $17.95 (1000-up, FOB USA).
