ADS8506IDWR

Analog To Digital Converters (ADC) Overview

The ADS8506IDWR is a single-supply, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates at a throughput rate of 40 kSPS with a typical power dissipation of 24 mW at full speed. The device features an internal 2.5-V reference and supports ±10 V, 4 V, and 5 V input ranges via external resistor networks. It provides both parallel and SPI-compatible serial interfaces for data output. The component is housed in a 28-pin SO package and is specified for operation over the -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'WR' corresponds to the tape and reel packaging format containing 1000 units per reel. Confirm the 'I' designation indicates the industrial temperature grade (-40°C to +85°C). Ensure the specific revision level matches the design requirements, as datasheet revisions may affect timing parameters.

Analog To Digital Converters (ADC) Selection Notes

Select this part when a low-power, single-supply 12-bit ADC is required with flexible interface options. The ADS8506 allows configuration for various voltage ranges using external resistors. Consider the 24-mW power consumption at 40 kSPS for battery-operated designs. Verify that the 28-pin SO package fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

The ADS8506 is pin-compatible with the ADS7806 and 16-bit variants like the ADS7807/8507. It belongs to the ADS8506 family of low-power sampling ADCs. The IDWR variant specifically denotes the industrial temperature range and tape-and-reel packaging, distinguishing it from the tube-packaged IDW version.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8506IBDWR is the high-precision alternative offering ±0.45 LSB INL/DNL compared to the ±0.9 LSB of the ADS8506IDWR. Both share identical pinouts and functionality but differ in linearity specifications.
