What are the key features of TLA2021IRUGR?
- 12-bit delta-sigma conversion with 3.03 µs maximum conversion time enables high-accuracy, fast-throughput single-channel ADC measurements
- Wide analog input range from -6.144 V to 5.5 V with integrated PGA allows direct connection to a broad range of sensor outputs without level-shifting
- Compact 10-pin QFN package with integrated voltage reference minimizes external component count and PCB footprint in space-constrained designs
What is TLA2021IRUGR used for?
The TLA2021IRUGR is ideal for precision analog-to-digital conversion in industrial sensor interfaces, portable test instruments, and IoT edge nodes that need 12-bit accuracy in a small footprint. Its wide input range of -6.144 V to 5.5 V makes it directly compatible with pressure, temperature, and load-cell bridge sensors without external amplifiers. The integrated voltage reference and PGA further simplify designs in battery-powered data loggers and wearable health-monitoring devices.

Frequently Asked Questions
How does the 3.03 µs maximum conversion time of TLA2021IRUGR affect throughput in a multi-point temperature monitoring system?
With a 3.03 µs maximum conversion time, the TLA2021IRUGR can theoretically complete over 300,000 conversions per second in single-shot mode, though the effective sample rate is governed by the selected oversampling ratio and communication overhead. For a 10-point temperature scan with I²C at 400 kHz, the practical per-channel update rate is around 100–200 Hz, which is more than adequate for thermal monitoring tasks with seconds-scale dynamics.
For a load-cell bridge measurement application, how does the -6.144 V minimum input of TLA2021IRUGR simplify the signal chain?
Load-cell bridge outputs are typically differential signals in the ±100 mV range riding on a common-mode voltage. The TLA2021IRUGR's -6.144 V to 5.5 V analog input range accommodates the full common-mode swing of a 5 V bridge excitation directly at the ADC inputs, eliminating the need for a separate instrumentation amplifier or level-shift circuit and reducing the BOM by 2 to 3 components.
How does the integrated voltage reference in TLA2021IRUGR reduce external component count compared to a discrete 12-bit ADC solution?
A standalone 12-bit ADC typically requires an external precision voltage reference IC (e.g., a 2.048 V or 4.096 V reference) plus at least 2 decoupling capacitors, adding 3 or more components. The TLA2021IRUGR's on-chip reference eliminates all of these, saving approximately 10–15 mm² of PCB area and reducing BOM cost by roughly $0.50 per unit in volume, while also avoiding reference-noise coupling issues common in multi-supply designs.
