Overview
The LTC2632CTS8-LZ10#TRMPBF is a dual 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 2.5V reference with a temperature coefficient of 10ppm/°C and operates on a single 2.7V to 5.5V supply. The device utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) of ±1 LSB, rail-to-rail output buffers, and guaranteed monotonicity. Upon power-up, the outputs reset to zero-scale in internal reference mode. It is housed in an 8-lead TSOT-23 package.
Feature Summary
- Dual 10-bit DACs with integrated 2.5V precision reference
- Maximum INL error of ±1 LSB and guaranteed monotonic operation
- 3-wire serial interface supporting clock rates up to 50MHz
- Power-on reset function clears outputs to zero-scale
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment
- Portable battery-powered equipment
Procurement Notes
Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration. Confirm that the 'C' grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the 'L' designation matches the required 2.7V to 5.5V supply voltage range for the application.
Selection Notes
Select this part when a dual-channel DAC with 10-bit resolution and low cost is required. The integrated 2.5V reference eliminates external components but limits the full-scale output span. Choose this over the 'H' grade if the system operates below 4.5V, as the 'H' grade requires a minimum of 4.5V supply voltage.
Part Context
This component belongs to the LTC2632 family, which offers various resolutions (8, 10, 12 bits) and reset configurations. The 'LZ10' variant specifically provides 10-bit resolution with a zero-scale power-on reset and a 2.5V internal reference. It shares the same 8-lead TSOT-23 footprint as other members of the series.
Replacement Considerations
Direct replacements within the same package and pinout include other LTC2632 variants such as the LTC2632CTS8-LI10 or LTC2632CTS8-LX10, provided the power-on reset behavior (mid-scale vs. zero-scale) and reference mode requirements are compatible.
