The MAX113/MAX117 are microprocessor-compatible, 8-bit, 4-channel and 8-channel analog-to-digital converters (ADCs). They operate from a single +3V supply and use a half-flash technique to achieve a 1.8µs conversion time (400ksps). A power-down pin (active-low PWRDN) reduces current consumption to 1µA typical. The devices return from power-down mode to normal operating mode in less than 900ns, allowing large supply-current reductions in Burst Mode® applications. (In Burst Mode, the ADC wakes up from a low-power state at specified intervals to sample the analog input signals.) Both converters include a track/hold, enabling the ADC to digitize fast analog signals.

Microprocessor (µP) interfaces are simplified because the ADC can appear as a memory location or I/O port without external interface logic. The data outputs use latched, three-state buffer circuitry for direct connection to an 8-bit parallel µP data bus or system input port. The MAX113/MAX117 input/reference configuration enables ratiometric operation.

The 4-channel MAX113 is available in a 24-pin DIP or SSOP. The 8-channel MAX117 is available in a 28-pin DIP or SSOP. For +5V applications, refer to the MAX114/MAX118 data sheet.

Features and Benefits

  • +3V (MAX117) or +5V (MAX118) Operation
  • Fully Assembled and Tested
  • On-Board Oscillator Generates Timing Signals
  • LED Display of Conversion Results
  • Low-Power Shutdown Mode

Product Detail

The MAX117 evaluation kit (EV kit) is a fully assembled evaluation board for the 8-bit, 8-channel, +3V MAX117 analog-to-digital converter. Channel selection can be controlled by switches located on the board or by user-provided logic-level signals. An on-board oscillator provides continuous conversions, and the conversion results appear on the LED output display.

The MAX117 EV kit also evaluates the +5V MAX118. To evaluate the MAX118, order a MAX118 free sample, replace the MAX117 with the MAX118, and install the appropriate R9 resistor (see Component List).
