Overview
The AD780CRZ-REEL7 is a pin-programmable, ultrahigh precision band gap voltage reference providing 2.5 V or 3.0 V outputs from input voltages between 4.0 V and 36 V. It features a maximum temperature coefficient of 3 ppm/°C and low output noise of 100 nV/√Hz. The device operates in series or shunt mode, sourcing or sinking up to 10 mA, and includes a dedicated temperature output pin. Packaged in an 8-Lead SOIC_N (SOIC-8) in a reel format, it is specified for operation from −40°C to +85°C.
Feature Summary
- Pin-programmable selection between 2.5 V and 3.0 V output configurations
- Ultralow drift performance with laser-trimmed initial accuracy
- Integrated temperature output pin for system monitoring
- Capable of stable operation in both series and shunt modes
Applications
- Precision references for high-resolution analog-to-digital converters
- Digital-to-analog converter reference circuits
- Temperature transducer applications utilizing the dedicated output pin
- General-purpose precision reference designs requiring low headroom
Procurement Notes
Verify the specific suffix REEL7 indicates the reel packaging configuration containing 1000 units per manufacturer specifications. Confirm RoHS compliance status as indicated by the Z designation in the base part number. Ensure the ordering documentation matches the required industrial temperature range and package type before finalizing procurement.
Selection Notes
Select this component when a low-headroom design is required to generate a 3.0 V reference from a 5.0 V supply. Consider the AD780CRZ-REEL7 for applications demanding minimal external components due to its integrated trim capabilities and stability under capacitive loads. Evaluate the trade-off between the 3 ppm/°C drift specification and cost compared to other grades in the family.
Part Context
This part belongs to the AD780 family of ultrahigh precision band gap references manufactured by Analog Devices Inc. It serves as a direct pin-compatible upgrade for legacy references such as the LT1019(A)–2.5 and the AD680. The CRZ variant specifically denotes the commercial grade operating within the −40°C to +85°C range, housed in an 8-lead SOIC package.
Replacement Considerations
The AD780BRZ-REEL7 is a confirmed substitute offering identical functionality with a tighter maximum temperature coefficient of 3 ppm/°C across the same operating range.
