PRODUCT OVERVIEW

What Is the ADS8317IBDGKR?

ADS8317IBDGKR is a 16-bit, high-speed, micropower sampling analog-to-digital converter (ADC) from Texas Instruments, specified for a supply voltage range from 2.7 V to 5.5 V[reference:0]. The device requires very little power, consuming only 10 mW at 5 V with a 250 kHz sampling rate, and as low as 0.2 mW at 2.7 V with a 10 kHz data rate[reference:1].

The ADS8317IBDGKR offers excellent linearity and very low noise and distortion[reference:2]. It features a synchronous serial (SPI/SSI-compatible) interface and a differential input[reference:3]. The reference voltage can be set to any level within the range of 0.1 V to V_DD/2[reference:4]. At lower data rates, the high speed of the device enables it to spend most of its time in power-down mode, significantly reducing average power dissipation[reference:5].

The device is available in an 8-pin MSOP (DGK) package and is pin-compatible with the ADS8321[reference:6]. Low power and small size make the ADS8317IBDGKR ideal for portable and battery-operated systems, remote data-acquisition modules, simultaneous multichannel systems, and isolated data acquisition[reference:7].

16-Bit Resolution No missing codes (full-supply range) with excellent linearity of ±0.8 LSB typ INL and ±0.7 LSB typ DNL.

microPower Consumption 10 mW at 5V/250kHz, 4 mW at 2.7V/200kHz, and 0.2 mW at 2.7V/10kHz.

Flexible Interface Synchronous serial (SPI/SSI-compatible) interface with differential input and adjustable reference voltage.

Circuit Considerations for ADS8317IBDGKR

Reference & Input Configuration

The ADS8317IBDGKR offers flexible reference and input configuration options:

Reference Voltage: External reference voltage can be set from 0.1 V to V_DD/2[reference:42]. The reference input current varies with sampling rate: 35 µA at 250 kHz, 25 µA at 200 kHz, 10 µA at 100 kHz, and 1 µA at 10 kHz[reference:43].
Differential Input: Full-scale range: +IN – (–IN) = ±V_REF. Absolute input range for +IN is –0.1 V to V_DD + 0.1 V[reference:44].
Input Impedance: Sampling input resistance is 50 Ω (typical) with 24 pF input capacitance[reference:45].
Power-Down Mode: The high-speed device spends most of its time in power-down mode at lower data rates, significantly reducing average power dissipation[reference:46].

PCB and Power-Supply Guidance

ADC performance depends on layout, bypassing, and power supply design:

Decouple the supply with a 0.1-µF ceramic capacitor placed as close to the V_DD pin as possible.
Use a ground plane for optimal noise performance.
Keep digital and analog signal paths separate to minimize coupling.
The serial interface is SPI/SSI-compatible with CMOS logic levels[reference:47][reference:48].
Thermal resistance θJA = 206.3°C/W for the MSOP-8 package[reference:49].
Verify the recommended PCB footprint from the official datasheet before production.
