Overview

  • AEC-Q100 Qualified for Automotive Applications
  • Integrated Precision Reference
    • 2.5V Full-Scale 10ppm/°C (LTC2634-L)
    • 4.096V Full-Scale 10ppm/°C (LTC2634-H)
  • Maximum INL Error: ±2.5 LSB (LTC2634-12)
  • Low Noise: 0.75mVP-P 0.1Hz to 200KHz
  • Guaranteed Monotonic over −40°C to 125°C Temperature Range
  • Selectable Internal or External Reference
  • 2.7V to 5.5V Supply Range (LTC2634-L)
  • Ultralow Crosstalk Between DACs (2.4nV•s)
  • Low Power: 0.6mA at 3V
  • Power-On Reset to Zero-Scale/Mid-Scale
  • Double Buffered Data Latches
  • Tiny 16-Lead 3mm × 3mm QFN and 10-Lead MSOP Packages

    • The LTC2634 is a family of quad 12-, 10- and 8-bit voltage output DACs with an integrated, high accuracy, low drift 10ppm/°C reference in 16-lead QFN and 10-lead MSOP packages. It has rail-to-rail output buffers and is guaranteed monotonic. The LTC2634-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2634-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the full-scale output to the external reference voltage.

    These DACs communicate via an SPI/MICROWIRE compatible 3-wire serial interface which operates at clock rates up to 50MHz. Serial data output (SDO), a hardware clear (CLR), and an asynchronous DAC update (LDAC) capability are available in the QFN package. The LTC2634 incorporates a power-on reset circuit. Options are available for reset to zero-scale or reset to mid-scale in internal reference mode, or reset to mid-scale in external reference mode after power-up.
