0.012% differential nonlinearity over the full commercial operating temperature range.
The DAC312 combines a 9-bit master D/A converter with a
3-bit (MSBs) segment generator to form an accurate 12-bit D/A
converter at low cost. This technique guarantees a very uniform
step size (up to ± 1/2 LSB from the ideal), monotonicity to
12-bits and integral nonlinearity to 0.05% at its differential current outputs. In order to provide the same performance with a …
