DESCRIPTION
The SGM71612R81/SGM71612R82/SGM71612R83 family is a 16-bit, 8 channels, voltage-output digital-to analog converter (DAC). These chips are guaranteed monotonic by design.
The SGM71612R81Z has an on-chip 1.25V 10ppm/℃ reference, giving a full-scale output range of 2.5V. The SGM71612R82Z/SGM71612R82M/SGM71612R83M have an on-chip 2.5V 10ppm/℃ reference, giving a full-scale output range of 5V.
The chips have a power-on control circuit, which can ensure that DAC has a fixed output when the system is powered on. The SGM71612R81Z and SGM71612R82Z output 0V when the system is powered up, and the SGM71612R82M/SGM71612R83M outputs mid-scale when the system is powered up.
The chips have an nLDAC pin that allows the DAC to update the output simultaneously. And the chips have an nCLR pin that allows the DAC to be updated to a configurable state, zero-code, mid-scale, or full-scale.
The SGM71612R81/SGM71612R82/SGM71612R83 family uses a 3-wire SPI-compatible interface, and its operation data rate is up to 50MHz.
The SGM71612R81Z and SGM71612R82Z are available in Green TSSOP-16, TQFN-4×4-16BL and FOCSP-2.6×2.6-16B packages. The SGM71612R82M and SGM71612R83M are available in Green TSSOP-16 and TQFN-4×4-16BL packages.
