Product details
Overview
ADS130B04QPWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified, 4-channel, simultaneous-sampling, 16-bit delta-sigma ADC with global-chop offset cancellation, 1.2-V internal reference, and integrated negative charge pump enabling sub-ground input measurements - deployed in battery current sensing, high-voltage resistor-divider monitoring, and thermistor-based temperature acquisition within BMS.
For engineers reviewing the ADS130B04QPWRQ1 datasheet, ADS130B04QPWRQ1 pinout, ADS130B04QPWRQ1 application, or ADS130B04QPWRQ1 equivalent, key selection criteria include simultaneous 4-channel sampling at up to 32 kSPS, programmable gain (1–128), crosstalk < –120 dB, low-drift offset (< ±0.4 µV with global-chop), and TSSOP-20 packaging for space-constrained automotive PCBs.
Technical Context
The ADS130B04QPWRQ1 implements four independent delta-sigma modulators with digital decimation filters per channel, supporting three power-scaling modes (high-resolution, low-power, very-low-power) tied to main clock frequency (8.192/4.096/2.048 MHz). Each channel features a dedicated PGA with eight selectable gains and configurable input multiplexer routing to analog inputs, AGND, or internal test signals.
It integrates a precision 1.2-V bandgap reference (±0.5% accuracy, 10 ppm/°C drift), internal oscillator (8.192 MHz ±0.5%), and CRC protection on SPI data and register map. The integrated negative charge pump enables absolute input voltages down to AGND – 0.3 V, eliminating need for bipolar supplies in shunt-based current measurement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit delta-sigma with 24-bit output word; effective resolution up to 16 bits at OSR=1024, gain=1. |
| Data rate | Up to 32 kSPS per channel in high-resolution mode; supports synchronized sampling across all 4 channels. |
| Input gain range | Programmable PGA gains of 1, 2, 4, 8, 16, 32, 64, 128 - sets full-scale differential input range from ±1.2 V (gain=1) to ±9.375 mV (gain=128). |
| Offset error (with global-chop) | ±0.4 µV input-referred max over –40°C to +125°C - enables stable zero-current detection in EV battery shunt monitoring. |
| Crosstalk | –120 dB between any two channels - ensures isolation critical for mixed-signal BMS measurements (e.g., voltage + current + temp on same die). |
| Supply range | 2.7 V to 3.6 V for both AVDD and DVDD - compatible with standard automotive 3.3-V rail without level-shifting. |
| Power consumption | 5 mW total at 3.3 V, 32 kSPS, gain=1 - enables thermal-constrained placement near battery cells. |
Pinout & Package
ADS130B04QPWRQ1 is housed in a 20-pin TSSOP package (6.50 mm × 4.40 mm), optimized for automotive thermal and layout constraints. Pin functions are validated per TI SBASAD2 datasheet Rev. November 2021.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN0P–AIN3N (pins 3–10) | Differential analog inputs | Four fully independent, high-impedance (≥300 MΩ with global-chop) input pairs for direct connection to shunts, dividers, or sensors. |
| AVDD / AGND (pins 1, 2) | Analog supply & ground | Separate analog domain with mandatory 1-µF decoupling; supports unipolar operation with integrated charge pump for sub-ground inputs. |
| DVDD / DGND (pins 20, 19) | Digital I/O supply & ground | Independent digital rail; allows AVDD/DVDD sequencing flexibility and reduces digital noise coupling into analog front-end. |
| SCLK / DIN / DOUT / CS (pins 14, 16, 15, 12) | SPI interface | Standard CPOL=0, CPHA=1 timing; DRDY (pin 13) provides hardware-ready handshake for deterministic data capture. |
| SYNC/RESET (pin 11) | Multi-device sync & reset | Active-low signal enabling precise time-aligned conversions across multiple ADS130B04QPWRQ1 devices in modular BMS stacks. |
| CLKIN (pin 17) | External clock input | Accepts 0.3–8.2 MHz clock; optional when internal 8.192-MHz oscillator is used - simplifies bill-of-materials. |
| CAP (pin 18) | LDO regulator output | Internal charge-pump output requiring 220-nF capacitor to DGND; enables negative input swing without external supply rails. |
Key Features
| Feature | Design Value |
|---|---|
| Global-chop offset cancellation | Reduces input-referred offset drift to ≤30 nV/°C and long-term drift to 0.25 µV over 1000 hours - eliminates recalibration in sealed BMS modules. |
| Integrated 1.2-V reference | Low-drift (10 ppm/°C), factory-trimmed reference eliminates external reference IC and associated layout area, cost, and thermal mismatch errors. |
| Simultaneous 4-channel sampling | Hardware-synchronized conversion start across all channels - preserves phase relationships essential for real-time SOC/SOH algorithms using voltage, current, and temperature. |
| CRC-protected SPI interface | Cyclic redundancy checks on register writes, reads, and data output prevent undetected communication corruption in noisy automotive ECU environments. |
| Three power-scaling modes | Configurable trade-off between noise (e.g., 0.42 µVRMS at OSR=16384) and throughput (32 kSPS max) - adapts to dynamic BMS operational states (sleep, charge, discharge). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS131B04QPWRQ1 | Same pinout, identical architecture, but includes built-in high-side current sense amplifier and enhanced diagnostic registers. | Better suited for designs requiring integrated current sense amplification and ASIL-D ready diagnostics. | Select ADS131B04QPWRQ1 if high-side sensing or advanced fault reporting (e.g., open-wire detection) is required; otherwise ADS130B04QPWRQ1 offers lower cost and simpler configuration. |
| MAX35104ATJ+ | 4-channel, 24-bit delta-sigma ADC with 125 kSPS max, wider supply range (2.7–5.5 V), no integrated charge pump or global-chop. | Targeted at industrial energy metering; lacks AEC-Q100 qualification and automotive temperature range. | Choose MAX35104ATJ+ only for non-automotive, higher-resolution applications where extended supply range matters more than automotive qualification or sub-ground input capability. |
Compared with ADS131B04QPWRQ1, the ADS130B04QPWRQ1 omits the high-side amplifier but retains identical core ADC performance, global-chop, and charge pump - making it optimal for cost-sensitive, space-constrained BMS nodes where external amplification is already present. Against MAX35104ATJ+, ADS130B04QPWRQ1 delivers automotive-grade reliability, lower system-level BOM count, and guaranteed sub-ground measurement capability.

FAQ
What is the maximum data rate supported by the ADS130B04QPWRQ1?
The ADS130B04QPWRQ1 supports up to 32 kSPS per channel in high-resolution mode with an 8.192-MHz master clock. This rate applies to all four channels simultaneously, preserving sample alignment for time-critical BMS calculations. Lower power modes reduce maximum data rate to 16 kSPS (low-power) and 8 kSPS (very-low-power), scaling with clock frequency while maintaining simultaneous sampling integrity.
Does the ADS130B04QPWRQ1 require an external reference voltage?
No, the ADS130B04QPWRQ1 integrates a precision 1.2-V low-drift bandgap reference with ±0.5% initial accuracy and 10 ppm/°C drift over –40°C to +125°C. This eliminates the need for external reference components, reduces PCB area, and avoids thermal tracking errors between reference and ADC - a key advantage in compact automotive BMS layouts.
How does the global-chop mode improve measurement stability in the ADS130B04QPWRQ1?
Global-chop mode in the ADS130B04QPWRQ1 actively cancels offset drift over temperature and time, reducing input-referred offset error to ±0.4 µV max and drift to ≤30 nV/°C. It also improves noise by √2 and extends long-term stability - critical for unattended BMS operation where recalibration is impractical and offset-induced SOC drift must be minimized.
Can the ADS130B04QPWRQ1 measure signals below ground potential?
Yes, the ADS130B04QPWRQ1 integrates a negative charge pump that generates a regulated negative voltage at the CAP pin, enabling absolute analog input voltages as low as AGND – 0.3 V. This allows direct measurement of bidirectional shunt currents using a single 3.3-V supply - eliminating need for dual-rail supplies or level-shifting circuitry in automotive battery monitoring.
Is the ADS130B04QPWRQ1 pin-compatible with other devices in the ADS13xB04 family?
The ADS130B04QPWRQ1 shares the same 20-pin TSSOP package and pinout with ADS131B04QPWRQ1, enabling drop-in replacement where high-side current sensing or enhanced diagnostics are not required. However, ADS130B04QPWRQ1 lacks the integrated high-side amplifier present in ADS131B04QPWRQ1 - functionality differences must be verified in system-level validation.
