1.8Msps, Single-Supply, Low-Power, TrueDifferential, 12-Bit ADCs with Internal Reference
General Description
The MAX1276/MAX1278 are low-power, high-speed, serial-output, 12-bit, analog-to-digital converters (ADCs) that operate at up to 1.8Msps and have an internal reference. 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 MAX1276/MAX1278 operate from a single +4.75V to +5.25V supply voltage. The MAX1276/MAX1278 include a 4.
