MAX1230

19-2852; Rev 1; 7/03 KIT ATION EVALU E L B AVAILA 12-Bit 300ksps ADCs with FIFO, Temp Sensor, Internal Reference General Description Features o Internal Temperature Sensor (±1°C Accuracy) o 16-Entry First-In/First-Out (FIFO) o Analog Multiplexer with True Differential Track/Hold 16-, 12-, 8-Channel Single Ended 8-, 6-, 4-Channel True Differential (Unipolar or Bipolar) o Accuracy: ±1 LSB INL, ±1 LSB DNL, No Missing Codes Over Temperature o Scan Mode, Internal Averaging, and Internal Clock o Low-Power Single +5V Operation 1.9mA at 300ksps o Internal 4.096V Reference or External Differential Reference o 10MHz 3-Wire SPI/QSPI/MICROWIRE-Compatible Interface o Space-Saving 28-Pin 5mm x 5mm QFN Package MAX1226/MAX1228/MAX1230 The MAX1226/MAX1228/MAX1230 are serial 12-bit analog-to-digital converters (ADCs) with an internal reference and an internal temperature sensor. These devices feature on-chip FIFO, scan mode, internal clock mode, internal averaging, and AutoShutdown™. The maximum sampling rate is 300ksps using an external clock. The MAX1230 has 16 input channels, the MAX1228 has 12 input channels, and the MAX1226 has 8 input channels. All input channels are configurable for single-ended or differential inputs in unipolar or bipolar mode. All three devices operate from a +5V supply and contain a 10MHz SPI™/QSPI™/MICROWIRE™-compatible serial port. The MAX1230 is available in 28-pin 5mm x 5mm QFN with exposed pad and 24-pin QSOP packages. The MAX1226/MAX1228 are only available...
