Product details
Overview
ADS8598SIPM from Texas Instruments is an 18-bit, 200-kSPS, 8-channel simultaneous-sampling SAR ADC with integrated analog front-end, ±10 V/±5 V bipolar input support on single 5-V supply, 1-MΩ input impedance, and on-chip 2.5-V reference - designed for high-accuracy power grid monitoring and protection relay systems.
For engineers reviewing the ADS8598SIPM datasheet, ADS8598SIPM pinout, ADS8598SIPM application, or ADS8598SIPM equivalent, this page delivers verified specifications, LQFP-64 pin mapping, real-world use cases in multichannel industrial DAQ, and two validated alternative parts with documented functional and interface differences.
Technical Context
The ADS8598SIPM implements true simultaneous sampling across all eight channels using dual independent CONVSTA/CONVSTB triggers, enabling zero-latency synchronized acquisition for phase-critical measurements. Each channel integrates a high-impedance (1 MΩ) programmable-gain amplifier, third-order LPF, overvoltage clamp, and dedicated ADC driver - eliminating external signal conditioning.
It supports three digital interface modes (parallel, serial, byte) via PAR/SER/BYTE_SEL, oversampling up to 16× via OS0–OS2 pins, and dual power-down states (standby/shutdown) controlled by STBY and RANGE pins - all operating across –40°C to +125°C with guaranteed performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 18-bit SAR ADC with no missing codes - ensures full dynamic range utilization without code gaps in precision measurement. |
| Throughput | 200 kSPS per channel, simultaneous across all 8 channels - enables real-time capture of fast transients in multi-phase systems. |
| Input Range | Pin-selectable ±10 V or ±5 V bipolar inputs - supports direct connection to CT/PT outputs without external level-shifting. |
| SNR / THD | 94 dB SNR and –109 dB THD typical - delivers >15.3 ENOB for high-fidelity waveform reconstruction in protection algorithms. |
| Reference | Integrated 2.5-V low-drift reference (7.5 ppm/°C) with buffered 4.0-V ADC reference voltage - eliminates external REF IC and reduces board area. |
| Input Impedance | 1 MΩ with ±7 ppm/°C drift - allows direct sensor/transformer interfacing while maintaining gain stability over temperature. |
| Operating Temp | –40°C to +125°C ambient - qualified for harsh industrial environments including outdoor substations and motor drive cabinets. |
Pinout & Package
LQFP-64 package (10.00 mm × 10.00 mm), thermally enhanced with exposed pad; requires AGND-connected thermal plane and decoupling per TI SBAS827 layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN_1P–AIN_8P AIN_1GND–AIN_8GND |
Differential analog inputs (8 channels) | True bipolar inputs accepting ±10 V or ±5 V; GND pins are dedicated low-impedance return paths for each channel's negative side. |
| CONVSTA / CONVSTB | Independent conversion start triggers | Enables simultaneous sampling: CONVSTA initiates conversion on channels 1–4; CONVSTB on channels 5–8 - critical for phase-aligned acquisition. |
| DB[15:0], DOUTA, DOUTB | Parallel/serial data outputs | 16-bit parallel output (DB0–DB15) or dual serial streams (DOUTA/DOUTB) - supports FPGA or microcontroller interfaces with minimal glue logic. |
| RANGE, STBY, RESET | Configuration & control inputs | RANGE selects input range or power mode; STBY enters standby/shutdown; RESET clears digital logic - all CMOS-compatible with 2.3–3.3-V I/O supplies. |
| REFCAPA / REFCAPB | Reference buffer decoupling terminals | Must be shorted and decoupled to AGND with 10-µF ceramic caps - stabilizes internal 4.0-V reference for ADC core accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated analog front-end per channel | Each of 8 channels includes PGA, 3rd-order LPF, clamp, and driver - removes need for 8 discrete op-amp/filter stages and saves >30 mm² PCB area. |
| Overvoltage input clamp with 9-kV ESD | Protects against transient surges on CT/PT lines without external TVS diodes - meets IEC 61000-4-5 Level 4 surge immunity requirements. |
| On-chip digital oversampling filter | Oversamples up to 16× (configurable via OS0–OS2) to boost SNR by 7.2 dB - achieves 101.8-dB SNR at 130 Hz without host processor overhead. |
| Flexible interface selection | PAR/SER/BYTE_SEL pin configures parallel (16-bit), serial (SPI-like), or byte-mode (two 8-bit reads) - simplifies integration with legacy 8-bit MCUs or modern FPGAs. |
| Zero-latency conversion architecture | No pipeline delay between sample and data ready - enables real-time closed-loop control in motor drives and active filters. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 18-bit simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8698IPM | 18-bit, 1-MSPS, single-ended inputs only; no integrated PGA or clamp; requires external reference. | Better suited for high-speed, single-ended sensor arrays where input protection and bipolar range are not required. | Select ADS8698IPM only when throughput >200 kSPS is mandatory and ±10-V bipolar input capability can be sacrificed. |
| AD7606C-18BSTZ | 18-bit, 1-MSPS, simultaneous sampling; ±10 V/±5 V inputs; but uses external 2.5-V reference and lacks on-chip oversampling filter. | Requires external REF and digital post-processing for oversampling; higher BOM count and layout complexity. | Choose AD7606C-18BSTZ if existing design already uses AD7606 family and needs higher speed, accepting added reference and filtering components. |
Compared with ADS8598SIPM, ADS8698IPM trades bipolar input flexibility and integrated protection for raw speed, while AD7606C-18BSTZ offers higher throughput but increases system-level design effort due to external reference dependency and absence of hardware oversampling.

FAQ
What is the maximum sampling rate per channel for the ADS8598SIPM?
The ADS8598SIPM achieves a maximum throughput of 200 kSPS per channel with simultaneous sampling across all eight channels. This rate is maintained without latency or pipeline delay, supporting real-time waveform capture for protection algorithms and power quality analysis. The device sustains this performance across its full –40°C to +125°C operating range when powered with AVDD = 4.75–5.25 V and DVDD = 2.3–3.3 V.
Does the ADS8598SIPM require an external reference voltage?
No, the ADS8598SIPM includes an integrated 2.5-V low-drift reference with 7.5 ppm/°C temperature coefficient and on-chip buffer, delivering a stable 4.0-V reference voltage to the ADC core via REFCAPA/REFCAPB pins. An external reference may be used by setting REFSEL = 0 and applying 2.475–2.525 V to REFIN/REFOUT, but it is not required - the internal reference meets full datasheet specifications.
How does the ADS8598SIPM handle bipolar input ranges?
The ADS8598SIPM supports pin-programmable bipolar inputs of ±10 V or ±5 V using a single 5-V analog supply. The RANGE pin selects the range when STBY is high; no external level-shifting circuitry is needed. Input clamps and 1-MΩ impedance allow direct connection to current transformers and potential transformers, preserving signal integrity and eliminating gain/offset errors from external drivers.
What digital interface options does the ADS8598SIPM support?
The ADS8598SIPM supports three configurable digital interfaces via the PAR/SER/BYTE_SEL pin: 16-bit parallel (DB[15:0]), serial (DOUTA/DOUTB with RD/SCLK as clock), and byte-mode (two 8-bit transfers). All modes share common control signals (CS, RESET, BUSY) and support simultaneous readout of all eight channels' data within one frame, enabling flexible host controller integration.
Is the ADS8598SIPM pin-compatible with other devices in the ADS85xx family?
No, the ADS8598SIPM is not pin-compatible with earlier ADS85xx-series devices such as ADS8588S or ADS8568. It features a unique 64-pin LQFP layout optimized for its dual-CONVST architecture, dedicated AIN_xP/GND pairs, and expanded digital interface pins (e.g., OS0–OS2, BYTE_SEL). Migration requires PCB redesign and firmware adaptation to leverage its simultaneous sampling and oversampling capabilities.
