Product details
Overview
LTC2411-1IMS#PBF from Analog Devices (formerly Linear Technology) is a 24-bit micropower delta-sigma analog-to-digital converter with differential input and reference, integrated oscillator, 2 ppm INL, 0.29 ppm RMS noise, and simultaneous 50 Hz/60 Hz rejection - designed for precision sensor digitization in industrial instrumentation and weight scales.
For engineers reviewing the LTC2411-1IMS#PBF datasheet, LTC2411-1IMS#PBF pinout, LTC2411-1IMS#PBF application, or LTC2411-1IMS#PBF equivalent, key selection criteria include its 10-lead MSOP package, –40°C to +85°C operating range, 2.7V–5.5V single supply, 4 µA sleep current, and FO-pin-configured 49 Hz–61.2 Hz notch rejection without external components.
Technical Context
The LTC2411-1IMS#PBF implements a decimating FIR filter with internal oscillator clocking at ~139.8 kHz, enabling single-cycle settling and no latency output. Its autocalibration engine performs offset and full-scale correction every conversion cycle, ensuring stability against temperature drift and supply variation.
It supports both internal and external clock modes via the FO pin; when FO = GND, it delivers simultaneous 50 Hz/60 Hz rejection over 49 Hz–61.2 Hz. The 3-wire SPI/MICROWIRE interface operates with SDO as three-state output and SCK as bidirectional clock, with mode auto-selected at power-up or CS falling edge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit with no missing codes - guarantees monotonicity and full dynamic range utilization for high-precision measurements. |
| INL | 2 ppm max over full temperature range - ensures linearity error ≤ ±0.0002% of full scale, critical for calibration-grade systems. |
| RMS Noise | 0.29 ppm of VREF (1.45 µVRMS at 5V ref) - enables sub-microvolt resolution in low-frequency sensor applications. |
| Common Mode Rejection | 140 dB DC - rejects common-mode interference from shared ground paths or remote sensing cables. |
| Supply Current | 4 µA in autosleep mode - extends battery life in portable or energy-harvested measurement nodes. |
| Input Range | ±0.5 × VREF differential, with independent VINCM and VREFCM from GND to VCC - supports ratiometric bridge sensing and wide common-mode voltage flexibility. |
| Notch Rejection | 87 dB min across 49 Hz–61.2 Hz (FO = GND) - eliminates mains-induced noise without external filtering or software post-processing. |
Pinout & Package
Package: 10-lead plastic MSOP (MS10), –40°C to +85°C operating temperature range, θJA = 120°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply input | 2.7V–5.5V single supply; requires local 10µF tantalum + 0.1µF ceramic bypass for stable ADC operation. |
| REF+ / REF– (Pins 2, 3) | Differential reference inputs | Accept 0.1V–VCC differential reference; enable ratiometric sensing and flexible gain scaling without external op-amps. |
| IN+ / IN– (Pins 4, 5) | Differential analog inputs | Support bipolar input range ±0.5×VREF with GND–VCC common-mode tolerance - ideal for strain gauges and load cells. |
| GND (Pin 6) | Analog/digital ground | Low-impedance connection point for star grounding; separates analog return from digital switching noise. |
| CS (Pin 7) | Active-low chip select | Wakes ADC from sleep, enables SDO, and triggers new conversion on rising edge - simplifies low-power polling architecture. |
| SDO (Pin 8) | Three-state serial data output | Outputs 32-bit conversion result LSB-first; high-Z when CS = HIGH - allows bus sharing with other SPI peripherals. |
| SCK (Pin 9) | Bidirectional serial clock | Auto-configures as input (external clock) or output (internal clock) based on power-up state - eliminates configuration registers. |
| FO (Pin 10) | Frequency control input | Selects internal oscillator mode: GND enables simultaneous 50/60 Hz rejection; external clock sets custom notch frequency at fEOSC/2560. |
Key Features
| Feature | Design Value |
|---|---|
| No-latency delta-sigma architecture | Single-cycle digital filter settling ensures each output corresponds exactly to the most recent input step - essential for multiplexed sensor arrays. |
| Per-conversion autocalibration | Continuous offset and full-scale correction eliminates long-term drift and reduces need for system-level recalibration in field-deployed instruments. |
| Flexible reference and input common-mode ranges | VINCM and VREFCM independently set from GND to VCC - supports direct connection to unbuffered bridges and thermocouples without level-shifting circuitry. |
| Internal oscillator with no external components | Eliminates crystal, capacitor, or resistor timing networks - reduces BOM count, PCB area, and qualification effort for medical and industrial certifications. |
| Simultaneous 50 Hz/60 Hz rejection | 87 dB min rejection across 49–61.2 Hz with FO = GND - meets IEC 61000-4-8 immunity requirements without hardware filters or firmware compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 24-bit delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS124S08IPWR | 24-bit, 4 kSPS, integrated PGA and burnout current sources; requires external reference; no built-in 50/60 Hz notch. | Optimized for RTD and thermocouple front-ends; lacks simultaneous dual-line rejection. | Choose for multi-channel sensor systems needing programmable gain and diagnostics - not for standalone line-noise-critical weigh scales. |
| MAX11206ETL+ | 24-bit, 10 SPS, 0.25 ppm RMS noise, 110 dB 50/60 Hz rejection; 12-lead TDFN; higher sleep current (12 µA). | Superior line rejection but slower throughput and larger package; no independent VREFCM/VINCM flexibility. | Prefer for ultra-low-noise lab-grade DVMs where size and power are secondary to rejection depth. |
Compared with ADS124S08IPWR and MAX11206ETL+, the LTC2411-1IMS#PBF uniquely combines simultaneous 50/60 Hz rejection, true independent common-mode range control, and 4 µA sleep current in a 10-lead MSOP - making it optimal for compact, battery-powered, mains-noise-prone industrial sensors.

FAQ
What is the operating temperature range of the LTC2411-1IMS#PBF?
The LTC2411-1IMS#PBF is rated for –40°C to +85°C operation, matching the "I" grade specification in the Linear Technology datasheet. This extended range supports deployment in industrial enclosures, outdoor instrumentation, and factory-floor automation systems where ambient temperatures exceed commercial limits. The part maintains full 24-bit performance and 2 ppm INL across this range.
How does the FO pin configure notch rejection on the LTC2411-1IMS#PBF?
On the LTC2411-1IMS#PBF, connecting the FO pin to GND configures the internal oscillator for simultaneous 50 Hz and 60 Hz rejection across 49 Hz–61.2 Hz (87 dB min). Unlike the LTC2411, the LTC2411-1IMS#PBF does not support separate 50 Hz or 60 Hz modes - FO = VCC or floating is undefined. External clocking via FO enables custom notch placement at fEOSC/2560.
Does the LTC2411-1IMS#PBF require external components for its oscillator?
No, the LTC2411-1IMS#PBF integrates a precision oscillator that requires no external crystals, capacitors, or resistors. When FO is tied to GND, the device self-configures to its default 139.8 kHz internal clock frequency, enabling immediate 49–61.2 Hz notch rejection. This eliminates timing-component qualification and improves long-term stability versus crystal-based solutions.
Can the LTC2411-1IMS#PBF interface directly with a 3.3V microcontroller SPI bus?
Yes, the LTC2411-1IMS#PBF supports 2.7V–5.5V operation and its digital I/O pins (CS, SCK, SDO) are fully compatible with 3.3V logic levels: VIH = 2.0V min and VOL = 0.4V max at 1.6 mA load. No level-shifting circuitry is needed when interfacing with standard 3.3V MCUs, and the 3-wire protocol avoids MISO/MOSI direction conflicts.
What is the maximum achievable effective resolution of the LTC2411-1IMS#PBF in practice?
The LTC2411-1IMS#PBF achieves 24-bit no-missing-codes resolution with 0.29 ppm RMS noise (≈1.45 µVRMS at 5V reference), translating to ~21.5 effective bits (ENOB) at DC. Its 2 ppm INL and per-conversion calibration ensure this resolution remains usable across temperature and time - unlike many 24-bit ADCs whose effective resolution degrades due to drift or missing codes near full scale.
