What are the key features of PAMC1035DR?
- 16-bit delta-sigma ADC modulator with ±1.25 V bipolar analog input range and 0.0183% maximum linearity error for precision measurement accuracy
- Integrated 2.5 V reference output eliminating the need for an external voltage reference and reducing BOM cost in single-channel data acquisition designs
- 8-pin SOIC (R-PDSO-G8) package with binary-coded single-channel output simplifying digital interface to DSPs and microcontrollers in compact signal chain layouts
What is PAMC1035DR used for?
The PAMC1035DR is designed for high-accuracy analog measurement in industrial process control, precision weigh scales, and pressure-sensing modules where a 16-bit delta-sigma conversion with ±1.25 V bipolar input is required. Its integrated 2.5 V reference and low linearity error of 0.0183% make it suitable as a front-end modulator in multi-channel data acquisition cards paired with digital filter DSPs or FPGAs. Medical diagnostic equipment and laboratory instruments that demand stable, low-drift ADC performance also benefit from the PAMC1035DR's delta-sigma architecture in a compact SOIC-8 footprint.

Frequently Asked Questions
What is the resolution and linearity error specification of the PAMC1035DR delta-sigma modulator?
The PAMC1035DR is a 16-bit delta-sigma modulator with a maximum linearity error of 0.0183%, equivalent to approximately 3 LSB at full scale. This precision level supports industrial weighing, pressure sensing, and laboratory measurement applications where high accuracy over the ±1.25 V bipolar input range is critical.
Does the PAMC1035DR include an internal voltage reference, and how does that simplify system design?
Yes, the PAMC1035DR integrates a 2.5 V reference output, eliminating the need for a discrete external voltage reference component. This reduces BOM cost and board area while ensuring a stable, matched reference voltage for the 16-bit delta-sigma conversion, particularly useful in compact single-channel 8-pin SOIC designs.
What analog input voltage range does the PAMC1035DR support, and which sensor types does it suit?
The PAMC1035DR accepts a bipolar analog input from -1.25 V to +1.25 V, directly compatible with bridge sensor outputs, strain gauges, and current-sensing shunt amplifiers that produce differential millivolt-to-volt signals around a 0 V midpoint. The 16-bit resolution resolves signal changes as small as approximately 38 µV across the full ±1.25 V range.
How does PAMC1035DR interface with a DSP or FPGA in a data acquisition system?
The PAMC1035DR produces a 1-bit binary-coded serial bitstream output compatible with standard delta-sigma decimation filter IP cores in FPGAs or dedicated sigma-delta DSP front ends. A 3-wire SPI-like serial interface carries the modulator output at typical oversampling rates, allowing the host to implement configurable digital filter bandwidths and achieve effective resolution up to 16 bits in a single-channel measurement chain.
