Overview
The LTC2632CTS8-LZ12#TRMPBF is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 2.5V full-scale 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 error of ±2.5LSB, a settling time of 4.4µs at 3V, and rail-to-rail output buffers. The part is housed in an 8-lead TSOT-23 package and includes a power-on reset function that clears outputs to zero-scale.
Feature Summary
- Dual 12-bit DACs with integrated 2.5V internal reference
- Maximum INL error of ±2.5LSB and guaranteed monotonicity
- Power-on reset to zero-scale for consistent initialization
- 3-wire serial interface supporting clock rates up to 50MHz
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
Procurement Notes
Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration. Confirm the 'C' grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure compatibility with the required 2.7V to 5.5V supply voltage and 3-wire SPI interface protocol before procurement.
Selection Notes
Select this component when a dual-channel DAC with low drift is required. The LZ12 suffix specifies a 12-bit resolution with zero-scale power-on reset behavior. Choose this over HI variants if the system operates below 4.5V, as H-grade parts require a minimum of 4.5V supply. Verify that the ±2.5LSB INL specification meets the application's accuracy requirements.
Part Context
This part belongs to the LTC2632 family of dual voltage-output DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset state (zero-scale or mid-scale). The LTSJ/LTFS markings on the package identify the specific variant within the series.
Replacement Considerations
Direct substitutes within the same family include LTC2632ACTS8-LZ12#TRMPBF, which offers improved linearity (±1.5LSB max INL) while maintaining identical pinout and functionality.
