Product details
Overview
ADS8586SIPMR from Texas Instruments is a 16-bit, simultaneous-sampling SAR ADC with integrated analog front-end for 6-channel bipolar data acquisition. It delivers 250 kSPS per channel, ±0.35 LSB DNL, 96.4 dB SNR (with 16× oversampling), and operates from a single 5-V analog supply while accepting ±10 V or ±5 V inputs-enabling direct connection to CT/PT sensors in high-voltage grid monitoring systems.
For engineers reviewing the ADS8586SIPMR datasheet, ADS8586SIPMR pinout, ADS8586SIPMR application, or ADS8586SIPMR equivalent, key selection criteria include simultaneous 6-channel sampling integrity, on-chip 2.5-V reference stability (7.5 ppm/°C drift), 1 MΩ input impedance, oversampling digital filter support, and flexible parallel/serial/byte interface compatibility with industrial real-time controllers.
Technical Context
The ADS8586SIPMR implements six independent analog signal chains-each with a clamp-protected, 1-MΩ-input-impedance PGA, third-order LPF, and dedicated ADC driver-feeding a shared 16-bit SAR core. Its dual CONVST inputs (CONVSTA/CONVSTB) enable precise interleaved or grouped channel triggering across all six channels without inter-channel skew.
Digital interface flexibility is achieved via three modes selected by PAR/SER/BYTE SEL: 16-bit parallel (DB[15:0]), serial (DOUTA/DOUTB with RD/SCLK clocking), or byte-mode (DB[7:0] + DB[15:8])-all synchronized to BUSY and FRSTDATA for deterministic timing in deterministic control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit SAR with no missing codes-ensures monotonicity and full-scale linearity for precision metrology. |
| Throughput | 250 kSPS per channel, simultaneous across all 6 channels-supports real-time protection relay response within 4 µs latency. |
| INL / DNL | ±0.45 LSB INL, ±0.35 LSB DNL-guarantees <0.001% gain/offset error contribution in closed-loop motor control feedback. |
| SNR | 96.4 dB (16× oversampling, 130 Hz)-enables >15.7 ENOB for high-fidelity waveform capture in power quality analyzers. |

| Reference | Integrated 2.5-V reference with 7.5 ppm/°C drift and 10-µF decoupling-reduces BOM count and improves thermal stability vs. external refs. |
| Supply | AVDD = 4.75–5.25 V; DVDD = 2.3–3.3 V-allows mixed-voltage host MCU interfacing without level shifters. |
| Temp Range | –40°C to +125°C-qualified for deployment inside outdoor switchgear enclosures and drive cabinets. |
Pinout & Package
ADS8586SIPMR is housed in a 64-pin LQFP package (10.00 mm × 10.00 mm), thermally optimized for industrial PCB layouts with multiple AGND/AVDD pins for low-noise analog partitioning and dedicated REFCAPA/REFCAPB pins requiring 10-µF ceramic decoupling to AGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN_1P to AIN_6P AIN_1GND to AIN_6GND |
6-channel differential analog inputs | Each pair accepts true bipolar ±10 V/±5 V; 1-MΩ input impedance enables direct transformer/sensor connection without buffer op-amps. |
| CONVSTA / CONVSTB | Asynchronous conversion start triggers | Independent control of first/second half of 6 channels-enables staggered sampling or grouped acquisition with zero inter-channel skew. |
| DB[15:0], DOUTA, DOUTB | Digital data outputs | Parallel 16-bit bus (DB[15:0]) or dual serial streams (DOUTA/DOUTB)-supports FPGA, DSP, or ARM Cortex-M with minimal glue logic. |
| PAR/SER/BYTE SEL RANGE OS0–OS2 |
Mode configuration inputs | Selects interface type (parallel/serial/byte), input range (±10 V/±5 V), and oversampling ratio (1×–16×)-all static at power-up or runtime reconfigurable. |
| BUSY / FRSTDATA | Status and sequencing indicators | BUSY asserts during conversion; FRSTDATA pulses on first valid channel read-enables lockstep DMA transfers without polling overhead. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, multi-channel SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8588SIPM | 8-channel, 200 kSPS/channel, same 16-bit SAR architecture but lower throughput and no OS2 pin for 16× oversampling. | Better channel density for space-constrained protection relays; sacrifices oversampling headroom and max sample rate. | Choose ADS8588SIPM only if 8-channel count outweighs need for 250 kSPS and advanced filtering. |
| AD7606C-16BSTZ | 6-channel, 16-bit, 1 MSPS/channel, but requires external ±15-V supplies for ±10-V input range and lacks integrated reference buffer. | Higher speed for transient capture; adds complexity with dual-supply design, external ref, and higher EMI susceptibility. | Choose AD7606C-16BSTZ only when >250 kSPS is mandatory and board area allows extra support components. |
Compared with ADS8586SIPMR, ADS8588SIPM trades throughput and oversampling capability for higher channel count, while AD7606C-16BSTZ demands more complex power and reference design to achieve higher speed-making ADS8586SIPMR the optimal balance of integration, precision, and industrial ruggedness for 6-channel grid and motor applications.

FAQ
What is the maximum sampling rate per channel for the ADS8586SIPMR?
The ADS8586SIPMR achieves a maximum throughput of 250 kSPS per channel with simultaneous sampling across all six channels. This rate is maintained under full-spec conditions: AVDD = 4.75–5.25 V, DVDD = 2.3–3.3 V, and operating temperature from –40°C to +125°C. The device guarantees zero-latency conversions and deterministic timing via BUSY and FRSTDATA signals-critical for real-time protection and control algorithms in the ADS8586SIPMR-based systems.
Does the ADS8586SIPMR require an external reference voltage?
No, the ADS8586SIPMR integrates a precision 2.5-V internal reference with 7.5 ppm/°C drift and includes a buffered output (REFIN/REFOUT) and dedicated decoupling pins (REFCAPA/REFCAPB). When REFSEL is high, the internal reference is enabled-eliminating the need for external references in most applications. An external reference (2.475–2.525 V) may be used by setting REFSEL low, but this does not improve performance and increases BOM cost and layout complexity for the ADS8586SIPMR.
How does the ADS8586SIPMR handle bipolar input ranges?
The ADS8586SIPMR supports true bipolar inputs of ±10 V or ±5 V using only a single 5-V analog supply. Input range selection is controlled by the RANGE pin: logic high selects ±10 V, logic low selects ±5 V. Each channel features independent AIN_nP and AIN_nGND terminals with 1-MΩ input impedance and integrated overvoltage clamps-allowing direct connection to current/voltage transformers without external level-shifting circuitry in ADS8586SIPMR implementations.
What digital interface options does the ADS8586SIPMR support?
The ADS8586SIPMR offers three hardware-configurable digital interfaces via the PAR/SER/BYTE SEL pin: 16-bit parallel (DB[15:0]), serial (DOUTA/DOUTB with RD/SCLK), or byte-mode (two 8-bit transfers). All modes use the same BUSY and FRSTDATA handshaking signals, enabling seamless migration between microcontroller platforms-from resource-constrained MCUs (serial) to high-throughput FPGAs (parallel)-without redesigning the ADS8586SIPMR signal chain.
Is the ADS8586SIPMR suitable for operation in high-temperature industrial environments?
Yes, the ADS8586SIPMR is fully specified from –40°C to +125°C ambient temperature and qualified for continuous operation in harsh environments such as outdoor switchgear, motor drive cabinets, and oil-filled transformers. Its analog performance-including ±0.45 LSB INL, 96.4 dB SNR, and <3 ppm/°C offset drift-is guaranteed across this full range, and its 64-pin LQFP package provides robust thermal dissipation (RθJA = 46.0°C/W) for reliable ADS8586SIPMR deployment without forced cooling.
