AD5343BRUZ-REEL

Digital To Analog Converters Overview

The AD5343BRUZ-REEL7 is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.5 V to 5.5 V supply, consuming 230 µA at 3 V and 300 µA at 5 V. The device features a parallel interface with double-buffered input logic for simultaneous updates via the LDAC pin. It includes on-chip rail-to-rail output buffer amplifiers and an asynchronous CLR facility. Power consumption reduces to 80 nA in power-down mode. The component is housed in a 20-lead TSSOP package and supports an operating temperature range of –40 °C to +105 °C.

Digital To Analog Converters Feature Summary

• Dual 12-bit resolution with guaranteed monotonicity by design
• Parallel data interface with double-buffered input registers
• Rail-to-rail output buffer amplifiers supporting 0–VREF or 0–2×VREF ranges
• Low power operation: 230 µA @ 3 V, down to 80 nA in power-down mode

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment circuits
• Programmable voltage and current sources
• Industrial process control systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel quantity. Ensure the B version temperature rating (-40 °C to +105 °C) matches the application requirements. Cross-reference the datasheet revision to confirm pinout and electrical specifications remain consistent with the intended design implementation.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel 12-bit DAC with a parallel interface is required. The AD5343 utilizes unbuffered reference inputs, unlike the AD5342 which offers buffered options. Consider the 20-lead TSSOP package constraints and the need for external decoupling capacitors (10 µF and 0.1 µF) on the VDD pin. Verify that the system logic levels align with the specified VIH and VIL thresholds for the chosen supply voltage.

Digital To Analog Converters Part Context

The AD5343 belongs to the AD5332/AD5333/AD5342/AD5343 family of dual DACs. It shares architectural similarities with the AD5342 but differs in package size and reference buffering capabilities. While the AD5342 uses a 28-lead TSSOP with buffered reference options, the AD5343 integrates into a compact 20-lead TSSOP with unbuffered references, targeting space-constrained designs requiring 12-bit precision.

Digital To Analog Converters Replacement Considerations

The AD5342 serves as a functional alternative within the same family, offering buffered reference inputs but requiring a 28-lead TSSOP package. For lower resolution needs, the AD5333 provides 10-bit performance in a 24-lead TSSOP. Direct pin-compatible replacements are not available due to the unique 20-lead configuration and parallel interface architecture of the AD5343.
