MULTIRANGE, 12-BIT DATA-ACQUISITION SYSTEM FITS IN 8-PIN µMAX PACKAGE
SUNNYVALE, CA-July 28, 2003-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX1272/MAX1273. Packaged in a small, 8-pin µMAX, these single-channel, multirange, 12-bit data-acquisition systems operate off a single 5V supply and convert at 87.5ksps. With four software-selectable input ranges, the MAX1272 accepts ±10V, ±5V, 0 to 10V, and 0 to 5V input signals, while the MAX1273 accepts ±VREF, ±VREF/2, 0 to VREF, and 0 to VREF/2. The MAX1272/MAX1273 are ideal for industrial control systems, data-acquisition systems, robotics, and medical instrumentation.
The MAX1272/MAX1273 incorporate input fault protection, an internal track/hold with an input bandwidth of 5MHz, and an internal 4.096V reference. Software-selectable input-range switching increases the effective dynamic range to 14 bits and enables these parts to measure input signals as large as _10V while operating from a +5V single supply.
The MAX1272/MAX1273 interface directly to SPI™/QSPI™ and MICROWIRE™ devices without additional circuitry. Software-selectable power-down modes result in currents as low as 1_A between conversions.
The MAX1272/MAX1273 are available in the commercial (0°C to +70°C) and extended (-40°C to +85°C) temperature ranges. Prices start at $6.98 (1000-up, FOB USA).
