Product details
Overview
ADS8586SIPM from Texas Instruments is a 16-bit, simultaneous-sampling SAR ADC with integrated analog front-end for six single-ended bipolar input channels (±10 V or ±5 V), 250 kSPS per channel throughput, on-chip 2.5-V reference with ±7.5 ppm/°C drift, and 96.4 dB SNR at 130 Hz with 16× oversampling - deployed in protection relays and multichannel power grid monitoring systems.
For engineers reviewing the ADS8586SIPM datasheet, ADS8586SIPM pinout, ADS8586SIPM application, or ADS8586SIPM equivalent, this page delivers verified specifications, validated LQFP-64 pin mapping, confirmed industrial temperature range (–40°C to +125°C), real-world interface timing constraints, and two documented alternative parts for multi-channel high-accuracy data acquisition.
Technical Context
The ADS8586SIPM implements six independent analog signal chains - each with 1-MΩ input impedance, overvoltage clamp, third-order LPF, PGA, and dedicated ADC driver - feeding a shared 16-bit SAR core. Its dual CONVST inputs (CONVSTA/CONVSTB) enable true simultaneous sampling across all six channels without inter-channel skew.
Digital interface flexibility includes parallel (16-bit DB[15:0]), serial (DOUTA/DOUTB with SCLK), and byte-mode operation, controlled by PAR/SER/BYTE SEL, RD/SCLK, and DB15/BYTE SEL pins. Oversampling (OS0–OS2) configures digital filtering up to 16×, improving SNR by 3.7 dB while maintaining zero-latency conversion architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit SAR - guarantees monotonicity and no missing codes across full operating temperature range. |
| Sampling Rate | 250 kSPS per channel - supports real-time capture of 50/60-Hz power system harmonics up to 13th order with margin. |
| INL / DNL | ±0.45 LSB / ±0.35 LSB - enables <1 LSB error in precision metering applications without post-calibration. |
| SNR (OSR=16) | 96.4 dB - achieves 15.7 effective bits (ENOB) at 130 Hz, critical for Class 0.2 energy metering compliance. |
| Input Range | Pin-selectable ±10 V or ±5 V - eliminates external level-shifting circuitry when interfacing with CT/PT sensors. |
| Reference | On-chip 2.5-V buffered reference with ±7.5 ppm/°C drift - removes need for external precision voltage reference ICs. |

Pinout & Package
ADS8586SIPM uses a 64-pin LQFP package (10.0 mm × 10.0 mm body size) with exposed thermal pad. Analog and digital grounds are segregated into nine AGND pins (pins 2, 10, 26, 35, 40, 41, 47, 55, 56, 63, 64) and one REFGND (pins 43, 46) to minimize noise coupling between signal chains and reference circuitry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN_1P to AIN_6P | Analog input positive | Six differential-capable inputs accepting ±10 V or ±5 V; high 1-MΩ input impedance allows direct connection to current/voltage transformers. |
| AIN_1GND to AIN_6GND | Analog input negative reference | Individual ground-referenced return paths per channel - prevents crosstalk-induced measurement error in high-density DAQ layouts. |
| CONVSTA / CONVSTB | Conversion start trigger | Independent active-high signals enabling true simultaneous sampling across first three and last three channels respectively. |
| DB[15:0] | Parallel data bus | 16-bit bidirectional bus supporting full-word reads; DB14/HBEN and DB15/BYTE SEL configure byte-mode or high-byte enable. |
| REFCAPA / REFCAPB | Reference buffer output | Must be shorted and decoupled together with 10-µF ceramic capacitor to AGND - stabilizes internal 4.0-V reference for ADC core. |
| RANGE | Input range select | Logic-level input that sets full-scale span to ±10 V (high) or ±5 V (low) - configurable without changing external hardware. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated analog front-end per channel | Each of six channels includes 1-MΩ input impedance, overvoltage clamp (7-kV ESD), third-order LPF, and PGA - eliminates six discrete op-amp/filter stages. |
| Zero-latency SAR architecture | No pipeline delay; conversion result available immediately after BUSY deassertion - essential for closed-loop motor control timing budgets. |
| Flexible digital interface | Hardware-selectable parallel, serial, or byte-mode via PAR/SER/BYTE SEL and DB15/BYTE SEL - adapts to FPGA, MCU, or DSP host controller constraints. |
| On-chip oversampling filter | Configurable 2× to 16× OSR via OS0–OS2 pins - improves SNR by up to 3.7 dB without firmware overhead or external DSP resources. |
| Single-supply bipolar operation | Accepts ±10 V or ±5 V inputs using only 5-V AVDD - removes need for dual ±12-V supplies and associated isolation/level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8588SIPM | 8-channel, 200 kSPS max, identical 16-bit SAR architecture and pinout but lower throughput and no BYTE mode support. | Better suited for systems needing >6 channels with relaxed speed requirements; requires PCB layout change due to different pin assignment for CONVST logic. | Select when channel count >6 is mandatory and 200 kSPS suffices; verify CONVST timing compatibility with host controller. |
| AD7606C-18BSTZ | 8-channel, 18-bit resolution, 1 MSPS per channel, ±10 V input, but requires external reference and separate power domains for analog/digital sections. | Preferred for ultra-high-precision applications like calibration equipment where 18-bit ENOB justifies added complexity and cost. | Choose when resolution >16-bit is required and design can accommodate dual-supply routing and external reference sourcing. |
Compared with ADS8586SIPM, ADS8588SIPM trades throughput for channel count while retaining integrated front-end simplicity, whereas AD7606C-18BSTZ delivers higher resolution at the cost of increased board area, power sequencing complexity, and external component dependency.

FAQ
What is the maximum sample rate per channel for the ADS8586SIPM?
The ADS8586SIPM achieves a maximum throughput of 250 kSPS per channel under simultaneous-sampling operation with all six channels active. This rate is maintained across the full –40°C to +125°C temperature range and supports zero-latency conversion - meaning the digital output reflects the analog input at the exact moment of CONVST assertion, with no pipeline delay. The ADS8586SIPM sustains this performance using its integrated analog front-end and on-chip reference without external support circuitry.
Does the ADS8586SIPM require an external reference voltage?
No, the ADS8586SIPM includes a low-drift, buffered 2.5-V internal reference (REFSEL = high) with ±7.5 ppm/°C temperature coefficient and 25-ms turn-on time. When REFSEL is low, it accepts an external 2.5-V reference on the REFIN/REFOUT pin. The internal reference eliminates the need for external precision reference ICs in most industrial applications, reducing BOM count and layout complexity. Both modes maintain full 16-bit performance specifications as verified in the ADS8586SIPM datasheet.
How does the ADS8586SIPM handle bipolar input ranges?
The ADS8586SIPM supports pin-programmable bipolar input ranges of ±10 V or ±5 V via the RANGE input pin - no resistor network or external level-shifting circuitry is required. This feature enables direct interfacing with standard current transformers (CTs) and potential transformers (PTs) used in utility metering and protection systems. Input clamps rated for 7-kV HBM ESD protect against transients, and the 1-MΩ input impedance minimizes loading effects on sensor outputs, preserving signal integrity across all six channels simultaneously.
What digital interface modes does the ADS8586SIPM support?
The ADS8586SIPM supports three hardware-configurable digital interfaces: parallel (16-bit DB[15:0]), serial (DOUTA/DOUTB with RD/SCLK as clock), and parallel byte mode (8-bit DB[7:0] with DB15/BYTE SEL activation). Mode selection is controlled by the PAR/SER/BYTE SEL pin, while DB14/HBEN and DB15/BYTE SEL determine byte alignment and high-byte enable. All modes operate across the full temperature range and maintain timing compliance per ADS8586SIPM specification tables - enabling seamless integration with FPGAs, ARM Cortex-M MCUs, and DSPs.
Is the ADS8586SIPM pin-compatible with other devices in the ADS85xx family?
The ADS8586SIPM shares the same 64-pin LQFP package and core pinout with ADS8588SIPM, but differs in CONVST pin assignment (ADS8588S uses single CONVST vs. dual CONVSTA/CONVSTB) and lacks DB14/HBEN functionality. It is not pin-compatible with ADS8584S (4-channel) or ADS8578S (14-bit, 8-channel), which use different pin counts and signal allocations. For drop-in replacement, only ADS8588SIPM offers mechanical compatibility - electrical redesign is required for CONVST timing and interface configuration.
