Overview
The LTC2633ACTS8-HZ12#TRMPBF is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1.5 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the –40°C to 125°C temperature range. Power-on reset defaults to zero-scale.
Feature Summary
- Dual 12-bit resolution with ±1.5 LSB maximum INL error
- Integrated 4.096V precision reference with 10ppm/°C drift
- Rail-to-rail output buffers with 4.7µs settling time at 5V
- Power-on reset to zero-scale for consistent initialization
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Power Supply Margining
- Portable Equipment
- Automotive Systems
Procurement Notes
Verify the #TRMPBF suffix indicates a 500-unit tape and reel configuration. Confirm the H-grade designation matches the required –40°C to 125°C operating temperature range. Ensure the Z power-on reset code aligns with system startup requirements for zero-scale outputs.
Selection Notes
Select this part when a 4.096V full-scale output is required with high accuracy (±1.5 LSB INL). The H-grade variant supports a 4.5V to 5.5V supply range, distinguishing it from L-grade parts that operate down to 2.7V. The TSOT-23 package offers a compact footprint for space-constrained designs.
Part Context
This component belongs to the LTC2633 family of dual DACs. Variants differ by resolution (8/10/12-bit), accuracy grade (standard vs A-grade), full-scale voltage (2.5V vs 4.096V), and power-on reset behavior. The ACTS8-HZ12 suffix specifies the A-grade accuracy, H-grade temperature range, and zero-scale reset function.
Replacement Considerations
Direct substitutes within the same family include LTC2633AHZ12#TRPBF (different packaging quantity) or LTC2633HIZ12#TRMPBF if mid-scale reset is acceptable. Cross-family replacements require verifying I²C compatibility and pinout alignment.
