TLV5621ED

Digital To Analog Converters Overview

The TLV5621ED is a low-power quadruple 8-bit digital-to-analog converter (DAC) from Texas Instruments. It features four buffered voltage output DACs with high-impedance reference inputs, operating on a single supply of 2.7 V to 5.5 V. The device utilizes a simple two-wire or three-wire serial interface for digital control and includes an internal power-on reset function. Each DAC output can be programmed for either one or two times the reference voltage range. The component is housed in a 14-terminal small-outline (D) package and is characterized for operation within the industry temperature range of –40°C to 85°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and shipping quantity. The 'ED' suffix indicates a tube package variant. Confirm availability status as product lifecycles may change. Ensure the selected part matches the required industrial temperature range and electrical specifications for the target application design.

Digital To Analog Converters Selection Notes

Select this component when multiple independent analog outputs are required from a single IC. The TLV5621ED supports both single-buffered and double-buffered serial modes, allowing flexibility in microcontroller interfacing. Consider the programmable output range feature if signal scaling is needed without external resistors. Verify that the load requirements fall within the specified source and sink current limits for the desired accuracy.

Digital To Analog Converters Part Context

The TLV5621ED belongs to the TLV562x family of low-power DACs. This family shares common architectural features such as resistor-string conversion and buffered outputs. The 'E' grade denotes the industrial temperature range, while the 'D' package specifies the small-outline integrated circuit form factor. Variants like the TLV5621ID offer identical electrical performance but may differ in packaging or testing configurations.

Digital To Analog Converters Replacement Considerations

The TLV5621ID serves as a parameter-equivalent alternative within the same package family. Both parts share identical electrical characteristics and pinouts. Verify that the specific ordering suffixes align with the required manufacturing and shipping formats before substitution.
