Frequently Asked Questions
How precise is the output voltage of the LT1004CPW-1-2 and what does that mean for ADC accuracy?
The LT1004CPW-1-2 delivers an output voltage between 1.231 V and 1.239 V with a nominal of 1.235 V, giving a tolerance of roughly ±4 mV. For a 12-bit ADC referenced to 1.235 V, this tolerance translates to less than 0.3% full-scale error, making it suitable for most precision measurement and instrumentation designs without external trimming.
For a coin-cell powered sensor node, how does the two-terminal shunt topology of the LT1004CPW-1-2 help reduce power consumption?
The two-terminal shunt configuration of the LT1004CPW-1-2 allows it to operate at very low bias currents, making it compatible with coin-cell and thin-film battery designs where every microamp counts. Since no additional external components are required, the total solution footprint is minimal, and the micropower quiescent drain keeps the 1.235 V reference stable for extended periods on a single battery cell.
What package does the LT1004CPW-1-2 use and how many pins does it have?
The LT1004CPW-1-2 comes in an 8-pin SOIC package, which provides a compact footprint of approximately 5 mm × 4 mm, easy to place on standard SMT assembly lines. Despite having 8 pins available, the two-terminal reference only uses 2 active connections, leaving the remaining pins as no-connects, which simplifies PCB routing in space-constrained designs.
