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 4.096V internal reference. The MAX1276 has a unipolar analog input, while the MAX1278 has a bipolar analog input. These devices feature a partial power-down mode and a full power-down mode for use between conversions, which lower the supply current to 2mA (typ) and 1µA (max), respectively. Also featured is a separate power-supply input (VL), which allows direct interfacing to +1.8V to VDD digital logic. The fast conversion speed, low-power dissipation, excellent AC performance, and DC accuracy (±1.25 LSB INL) make the MAX1276/MAX1278 ideal for industrial process control, motor control, and base-station applications.
The MAX1276/MAX1278 come in a 12-pin TQFN package, and are available in the extended (-40°C to +85°C) temperature range.

MAX1276EVKIT
Evaluation Kit/Evaluation System for the MAX1070, MAX1071, MAX1072, MAX1075–MAX1079, MAX1224, MAX1225, and MAX1274–MAX1279
Product Detail
The MAX1276 evaluation kit (EV kit) consists of an assembled board that can be used with a logic analyzer for high-speed evaluation of the MAX1276 family of devices at conversion rates up to 1.8Msps. The MAX1276 EV kit can be used together with a Maxim 68HC16MODULE-DIP microcontroller (µC) module for a complete MAX1276 200ksps evaluation system (EV system). Windows® 98/ME/XP software provides a convenient user interface to exercise the MAX1276 and other 5V family members (see Table 4). When used with a logic analyzer, the EV kit can be used to evaluate any of the following parts; MAX1070/MAX1071/MAX1072/MAX1075–MAX1079/MAX1224/MAX1225/MAX1274–MAX1279, by replacing the MAX1276 with the desired device.
Order the EV kit (MAX1276EVKIT) for use with a logic analyzer or if the 68HC16MODULE-DIP has been purchased with a previous Maxim EV system. Order the complete MAX1276 EV system (MAX1276EVC16) to receive both the MAX1276 EV kit and 68HC16 boards for use with a personal computer.
To evaluate other members of the family, request a free sample and see the Evaluating Other Devices section for instructions.
