LTC2630ISC6-LM8#TRPBF

Overview

The LTC2630ISC6-LM8#TRPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision 2.5V reference with a 10ppm/°C temperature coefficient and operates within a 2.7V to 5.5V supply range. The device features a rail-to-rail output buffer, guaranteed monotonicity, and a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. It includes power-on reset options for zero or mid-scale initialization and double-buffered data latches. Packaged in a compact 6-lead SC70 format, it consumes 180µA at 3V and supports power-down modes.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with ±0.5 LSB DNL and ±0.5 LSB INL
• 3-wire serial interface (SPI/MICROWIRE) with 50MHz clock capability
• Power-on reset to zero scale or mid-scale

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the 'I' grade designation matches the required -40°C to 85°C operating temperature range for the application environment. Ensure the 8-bit resolution meets system accuracy requirements before procurement.

Selection Notes

Select this part when an 8-bit resolution is sufficient for the application's voltage control needs. The LM suffix indicates a mid-scale power-on reset, which may be preferred over zero-scale depending on downstream circuit sensitivity. Verify that the 2.5V full-scale output aligns with the input range of subsequent stages or ADCs.

Part Context

This component belongs to the LTC2630 family, which offers various combinations of resolution (8, 10, 12 bits), full-scale voltages (2.5V or 4.096V), and power-on reset behaviors. The ISC6 package denotes the 6-lead SC70 form factor suitable for space-constrained designs. The LM8 variant specifically provides 8-bit resolution with mid-scale reset and 2.5V full-scale output.

Replacement Considerations

Direct substitutes within the same family include LTC2630ISC6-HM8#TRPBF (4.096V FS, requires 4.5V-5.5V supply) or LTC2630ISC6-LZ8#TRPBF (zero-scale reset). Cross-family replacements require verification of pin compatibility, interface protocols, and electrical specifications.
