Product details
Overview
LTC2415IGN#PBF from Analog Devices (formerly Linear Technology) is a micropower 24-bit delta-sigma analog-to-digital converter with differential input and reference, 2ppm INL, 0.23ppm RMS noise, and single-cycle settling time. It operates from 2.7V to 5.5V, supports 50Hz/60Hz notch filtering via internal oscillator, and targets precision sensor digitization in industrial instrumentation and weigh scales.
For engineers reviewing the LTC2415IGN#PBF datasheet, LTC2415IGN#PBF pinout, LTC2415IGN#PBF application, or LTC2415IGN#PBF equivalent, key selection considerations include its 15Hz output rate, GND-to-VCC common-mode input/reference range, 140dB DC common-mode rejection, and SSOP-16 package compatibility with SO-8 footprints.
Technical Context
The LTC2415IGN#PBF implements a delta-sigma modulator with decimating FIR filter and integrated auto-calibration DAC, enabling true no-latency conversion with guaranteed no missing codes. Its digital filter nulls at 50Hz or 60Hz ±2% depending on FO pin state, using an internal oscillator that requires no external components.
It uses a 3-wire SPI/MICROWIRE-compatible interface with bidirectional SCK and active-low CS, supporting both internal clock (SCK output) and external clock (SCK input) modes. The converter maintains independent GND-to-VCC setting for VINCM and VREFCM, enabling flexible ratiometric and remote sensing configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit with no missing codes-guarantees monotonicity and full dynamic range utilization. |
| INL | 2 ppm of VREF-enables 0.00005% linearity error in high-precision bridge sensor measurements. |
| RMS Noise | 0.23 ppm of VREF-supports sub-microvolt resolution in low-frequency industrial sensing. |
| Output Rate | 15 Hz-optimized for stable, low-drift readings in weight scales and temperature monitoring. |
| Supply Range | 2.7 V to 5.5 V-allows direct operation from single Li-ion, 3.3 V, or 5 V rails without regulation. |
| Common-Mode Rejection | 140 dB DC-rejects ground bounce and supply coupling in noisy industrial environments. |
| Notch Frequency | 50 Hz or 60 Hz ±2%-eliminates mains interference without external clocking components. |
Pinout & Package
Package: 16-lead plastic SSOP (GN), 0.150" wide, SO-8 footprint compatible, –40°C to +85°C operating range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,7,8,9,10,15,16) | Ground reference | Seven dedicated ground pins ensure low-impedance return paths for analog/digital currents and optimal VCC decoupling. |
| VCC (Pin 2) | Positive supply | Accepts 2.7–5.5 V; requires local 10 µF tantalum + 0.1 µF ceramic bypass to Pin 1 GND. |
| REF+ / REF– (Pins 3,4) | Differential reference inputs | Support 0.1 V to VCC differential range; VREFCM independently set from GND to VCC. |
| IN+ / IN– (Pins 5,6) | Differential analog inputs | Full-scale range = ±0.5 × VREF; VINCM independently set from GND–0.3 V to VCC+0.3 V. |
| FO (Pin 14) | Frequency control | FO = VCC → 50 Hz notch; FO = GND → 60 Hz notch; FO = external clock → fEOSC/2560 notch. |
| CS (Pin 11) | Chip select | Active-low; initiates data output and wakes ADC from sleep (20 µA); HIGH enables auto-shutdown. |
| SDO (Pin 12) | Serial data output | 3-state output; holds conversion result during sleep; outputs 32-bit data on falling SCK edges. |
| SCK (Pin 13) | Serial clock | Bidirectional: outputs internal clock (19.2 kHz) when idle, accepts external clock up to 2 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle settling time | Enables true multiplexed operation-no delay between channel changes or repeated conversions. |
| Internal oscillator | Eliminates crystals, capacitors, or external clocks-reduces BOM count and layout complexity. |
| Differential input & reference | Supports isolated, ratiometric, and remote-sensing topologies with independent common-mode voltage control. |
| 140 dB DC common-mode rejection | Rejects ground shifts and supply ripple in battery-powered or long-cable sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS124S08IPW | 24-bit, 4 kSPS max, integrated PGA and sensor bias, 1.8–3.6 V supply only | Requires external reference; lacks built-in 50/60 Hz notch; better for multi-channel sensor arrays | Select for systems needing programmable gain and on-chip excitation, but accept higher power and no auto-notch. |
| MAX11206ETL+ | 24-bit, 10 SPS, 1.8–3.6 V, 0.15 ppm RMS noise, no internal oscillator | Requires external crystal; lower noise but no 50/60 Hz rejection; smaller 16-pin TQFN | Select when ultra-low noise dominates over mains rejection, and external clock is acceptable. |
Compared with ADS124S08IPW and MAX11206ETL+, the LTC2415IGN#PBF delivers unique 50/60 Hz notch capability with zero external components, making it optimal for cost-sensitive, single-channel industrial sensors where mains interference is dominant and supply voltage exceeds 3.6 V.

FAQ
What is the maximum output data rate of the LTC2415IGN#PBF?
The LTC2415IGN#PBF has a fixed output data rate of 15 Hz when using its internal oscillator. This rate is determined by the internal digital filter structure and cannot be increased via external clocking-the device is optimized for stability and noise performance at this rate, not speed. The LTC2415IGN#PBF achieves single-cycle settling, meaning each 15 Hz reading corresponds directly to one complete conversion without latency or averaging delay.
How does the FO pin configure 50Hz vs 60Hz rejection on the LTC2415IGN#PBF?
On the LTC2415IGN#PBF, the FO pin selects the notch frequency of the internal digital filter: tying FO to VCC configures 50 Hz rejection, while tying FO to GND configures 60 Hz rejection. This is specific to the LTC2415 variant (not LTC2415-1). The LTC2415IGN#PBF does not support simultaneous 50/60 Hz rejection-that function belongs to the LTC2415-1 version. No external components are needed for either configuration.
Does the LTC2415IGN#PBF require an external reference voltage?
No, the LTC2415IGN#PBF does not require an external reference-it accepts any differential reference voltage from 0.1 V to VCC, and supports fully ratiometric operation where the reference is derived from the same supply as the sensor. However, an external reference can be used for improved absolute accuracy; the LTC2415IGN#PBF's reference inputs (REF+ and REF–) are fully differential and support independent common-mode voltage setting from GND to VCC.
What is the purpose of the seven GND pins on the LTC2415IGN#PBF SSOP package?
The seven GND pins (Pins 1, 7, 8, 9, 10, 15, 16) on the LTC2415IGN#PBF provide separate low-impedance return paths for analog, digital, and substrate currents, minimizing ground bounce and crosstalk. All seven must be connected to a solid ground plane-this layout practice ensures optimal PSRR, CMRR, and noise performance, especially critical for 24-bit resolution. The pinout reflects internal partitioning, not redundancy.
Can the LTC2415IGN#PBF operate from a 3.3 V supply while maintaining full 24-bit performance?
Yes, the LTC2415IGN#PBF is fully specified from 2.7 V to 5.5 V, including all key parameters (2ppm INL, 0.23ppm RMS noise, 140 dB CMRR) at 3.3 V. Electrical characteristics tables confirm performance across the entire supply range, and typical performance graphs (e.g., G19, G21) show noise and offset stability at 3.3 V. The device's internal oscillator and reference rejection remain effective at 3.3 V, making it suitable for modern low-voltage industrial and portable systems.
