1.5Msps, Single-Supply, Low-Power, TrueDifferential, 12-Bit ADCs with Internal Reference
General Description
The MAX1277/MAX1279 are low-power, high-speed, serial-output, 12-bit, analog-to-digital converters (ADCs) with an internal reference that operates at up to 1.5Msps. These devices feature true-differential inputs, offering better noise immunity, distortion improvements, and a wider dynamic range over single-ended inputs. A standard SPI™/QSPI™/MICROWIRE™ interface provides the clock necessary for conversion. These devices easily interface with standard digital signal processor (DSP) synchronous serial interfaces. The MAX1277/MAX1279 operate from a single +2.7V to +3.6V supply voltage. The MAX1277/MAX1279 include a 2.048V internal reference.
