Product details
Overview
LTC2411-1CMS#TRPBF from Analog Devices (formerly Linear Technology) is a 24-bit micropower delta-sigma analog-to-digital converter with differential input and reference, integrated oscillator, 0.29ppm RMS noise, 2ppm INL, and simultaneous 50Hz/60Hz rejection-designed for high-precision sensor digitization in weight scales and strain gauge transducers.
For engineers reviewing the LTC2411-1CMS#TRPBF datasheet, LTC2411-1CMS#TRPBF pinout, LTC2411-1CMS#TRPBF application, or LTC2411-1CMS#TRPBF equivalent, key selection criteria include its 49Hz–61.2Hz notch rejection profile, GND-to-VCC common-mode input/reference flexibility, single-cycle settling, and MSOP-10 package compatibility with low-noise industrial signal chains.
Technical Context
The LTC2411-1CMS#TRPBF implements a decimating FIR digital filter synchronized to an internal oscillator configured for simultaneous 50Hz/60Hz line-frequency rejection-achieving ≥87dB normal-mode rejection across 49Hz–61.2Hz without external components. Its auto-calibration engine performs offset and full-scale correction every conversion cycle.
It operates in three deterministic states-conversion, sleep (4µA), and data output-with no latency between input step and valid 32-bit output. The 3-wire SPI/MICROWIRE interface supports both internal SCK (17.5kHz) and external clock modes, with FO pin hardwired to GND to enable the LTC2411-1's dual-notch behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit, no missing codes-guarantees monotonicity and full dynamic range utilization in precision measurement. |
| INL | 2ppm max over temperature-enables 6½-digit DVM accuracy without system-level linearization. |
| RMS Noise | 0.29ppm of VREF (1.45µVRMS at 5V)-supports sub-microvolt signal resolution in low-bandwidth sensor interfaces. |
| Normal-Mode Rejection | ≥87dB from 49Hz to 61.2Hz-rejects AC mains interference in unshielded industrial environments without external filtering. |
| Supply Current | 200µA in conversion mode, 4µA in autosleep-extends battery life in portable instrumentation and remote sensors. |
| Input Range | ±0.5VREF differential, with independent VINCM and VREFCM from GND to VCC-enables ratiometric bridge sensing and ground-referenced reference designs. |
| Reference Range | 0.1V to VCC-allows direct use of low-voltage references (e.g., 1.25V bandgap) while maintaining full 24-bit resolution. |
Pinout & Package
Package: 10-lead plastic MSOP (MS10), 3mm × 3mm, 0.5mm pitch, RoHS-compliant, rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply rail | 2.7V–5.5V single supply; requires local 10µF tantalum + 0.1µF ceramic bypass for low-noise ADC performance. |
| REF+ / REF– (Pins 2, 3) | Differential reference inputs | Accept 0.1V–VCC differential voltage; common-mode independently set from GND to VCC-enables remote sensing and ratiometric configurations. |
| IN+ / IN– (Pins 4, 5) | Differential analog inputs | Support ±0.5VREF full-scale range; input common-mode rejection >140dB DC enables high CMRR in noisy environments. |
| GND (Pin 6) | Analog/digital ground | Single ground plane connection required; low-impedance path essential for noise immunity and INL stability. |
| CS (Pin 7) | Active-low chip select | Wakes ADC from 4µA sleep; initiates data output on falling edge; aborts transfer on rising edge during readout. |
| SDO (Pin 8) | 3-state serial data output | Outputs 32-bit conversion result MSB-first; high-Z when CS = HIGH-enables bus sharing with other SPI peripherals. |
| SCK (Pin 9) | Bidirectional serial clock | Functions as output (internal mode, 17.5kHz) or input (external mode); weak internal pull-up active in internal mode. |
| FO (Pin 10) | Frequency control input | Hardwired to GND to activate LTC2411-1's simultaneous 50Hz/60Hz rejection; not used with external oscillator. |
Key Features
| Feature | Design Value |
|---|---|
| No-latency delta-sigma architecture | Single-cycle digital filter settling ensures each output corresponds precisely to its input sample-critical for multiplexed sensor arrays. |
| Per-conversion auto-calibration | Continuous offset and full-scale correction eliminates drift-induced errors over time, temperature, and supply variation. |
| Flexible common-mode handling | Independent VINCM and VREFCM ranges (GND to VCC) support grounded reference + floating bridge topologies in one IC. |
| Integrated oscillator | Eliminates external crystal or clock source-reduces BOM count, PCB area, and EMI risk in space-constrained designs. |
| Low-power sleep mode | 4µA quiescent current enables multi-year battery operation in wireless sensor nodes and portable test equipment. |

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, 4kSPS, integrated PGA and burnout current sources; requires external reference; no built-in 50/60Hz notch. | Optimized for RTD and thermocouple front ends; lacks simultaneous dual-line rejection. | Select when programmable gain or sensor excitation is needed; avoid if line-frequency rejection is primary requirement. |
| LTC2440CG#PBF | 24-bit, 128SPS, 110dB 50/60Hz rejection (single-frequency selectable), higher 0.5ppm noise, 350µA conversion current. | Offers pin-selectable 50Hz or 60Hz notch only-not simultaneous rejection across 49–61.2Hz. | Choose for legacy LTC2411-compatible designs needing identical pinout but single-frequency filtering. |
Compared with ADS124S08IPWR and LTC2440CG#PBF, the LTC2411-1CMS#TRPBF uniquely delivers guaranteed simultaneous 50Hz/60Hz rejection in a micropower MSOP-10 package-making it optimal for global industrial equipment where mains frequency varies by region and board space is constrained.

FAQ
What is the function of the FO pin on the LTC2411-1CMS#TRPBF?
The FO (Frequency Oscillator) pin on the LTC2411-1CMS#TRPBF must be tied to GND to activate its simultaneous 50Hz/60Hz rejection mode. Unlike the LTC2411, which uses FO = GND for 60Hz or FO = VCC for 50Hz, the LTC2411-1CMS#TRPBF achieves ≥87dB rejection across 49Hz–61.2Hz only when FO = GND. Leaving FO floating or connecting it to VCC disables the dual-notch feature and may cause undefined behavior.
Does the LTC2411-1CMS#TRPBF require external passive components for its internal oscillator?
No, the LTC2411-1CMS#TRPBF does not require external passive components for its internal oscillator. The oscillator is fully integrated and factory-trimmed-no crystals, capacitors, or resistors are needed. This simplifies layout, reduces BOM cost, and improves reliability in vibration-prone or high-humidity environments where external crystals may fail.
Can the LTC2411-1CMS#TRPBF operate with a 1.8V supply?
No, the LTC2411-1CMS#TRPBF cannot operate with a 1.8V supply. Its absolute minimum supply voltage is 2.7V, and maximum is 5.5V per Absolute Maximum Ratings. Operation below 2.7V risks improper internal biasing, failed auto-calibration cycles, and invalid conversion results. For 1.8V systems, consider the AD779x series or ADS122C04, which support lower supply rails.
How does the LTC2411-1CMS#TRPBF achieve "no latency" in its delta-sigma architecture?
The LTC2411-1CMS#TRPBF achieves true no-latency operation by ensuring that each 32-bit output corresponds exactly to the analog input sampled during that single conversion cycle-without filter settling delay or redundant data. Its decimating FIR filter is synchronized to the internal oscillator such that the output is valid immediately after the data output period begins, enabling reliable multiplexing and real-time response.
What is the maximum recommended reference voltage for the LTC2411-1CMS#TRPBF?
The maximum recommended reference voltage for the LTC2411-1CMS#TRPBF is equal to VCC, as specified in the Electrical Characteristics table: VREF = REF+ – REF– must be ≤ VCC and ≥ 0.1V. Using VREF = VCC maximizes SNR and effective resolution (e.g., 5V reference yields ~0.3µV LSB at 24 bits), provided the reference source can drive the 6pF REF+ and REF– input capacitance without droop.
