MAX1295 - 12-Bit ADCs

General Description

The MAX1295/MAX1297 low-power, 12-bit analog-todigital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed 12-bit parallel interface.

They operate with a single +2.7V to +3.6V analog supply.

Key Features

  • 12-Bit Resolution, ±0.5 LSB Linearity.
  • +3V Single-Supply Operation.
  • Internal +2.5V Reference.
  • Software-Configurable Analog Input Multiplexer 6-Channel Single-Ended/ 3-Channel Pseudo-Differential (MAX1295) 2-Channel Single-Ended/ 1-Channel Pseudo-Differential (MAX1297).
  • Software-Configurable Unipolar/Bipolar Analog Inputs.
  • Low Current 1.9mA (265ksps) 1.0mA (100ksps) 400µA (10ksps) 2µA (Shutdown).
  • Internal 3MHz Full-Power Bandwidth Tr.

19-1530; Rev 3; 12/02 EVAALVUAAILTAIOBNLEKIT 265ksps, +3V, 6-/2-Channel, 12-Bit ADCs with +2.5V Reference and Parallel Interface MAX1295/MAX1297 General Description The MAX1295/MAX1297 low-power, 12-bit analog-todigital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed 12-bit parallel interface. They operate with a single +2.7V to +3.6V analog supply. Power consumption is only 5.4mW at the maximum sampling rate of 265ksps. Two software-selectable power-down modes enable the MAX1295/MAX1297 to be shut down between conversions; accessing the parallel interface returns them to normal operation.
