Product details
Overview
LTC1415CG#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1.25 Msps successive-approximation ADC with true differential inputs, ±0.35 LSB INL, 72 dB S/(N+D) at 100 kHz, and 55 mW power dissipation on a single 5 V supply. It integrates internal reference (2.500 V), trimmed clock, and sample-and-hold - enabling high-fidelity data acquisition in imaging systems and DSP front-ends.
For engineers reviewing the LTC1415CG#TRPBF datasheet, LTC1415CG#TRPBF pinout, LTC1415CG#TRPBF application, or LTC1415CG#TRPBF equivalent, key selection criteria include its 18 MHz analog input bandwidth, 60 dB common-mode rejection up to 1 MHz, Nap/Sleep shutdown modes (down to 1 µA), and 28-pin SOIC (G) package compatibility with microprocessor/DSP parallel interfaces.
Technical Context
The LTC1415CG#TRPBF employs a capacitive DAC-based successive approximation architecture with a fully differential sample-and-hold that acquires signals within 150 ns and completes conversion in 700 ns. Its internal 2.500 V bandgap reference is amplified 1.638× to generate a precise 4.096 V full-scale range, supporting both internal and external reference operation.
It features µP-compatible parallel output (12-bit, three-state), asynchronous control via CONVST/BUSY/RD/CS, and separate OVDD logic supply (3 V or 5 V). The differential input structure rejects common-mode noise while maintaining ±0.25 LSB DNL and 80 dB THD at 100 kHz - critical for undersampling and high-dynamic-range signal capture.
Key Specifications

Pinout & Package
Package: 28-pin plastic SOIC (Wide), RoHS-compliant, body width 7.6 mm (G suffix per ordering guide).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +AIN (1) | Differential analog input positive | Accepts 0–4.096 V signal; sampled simultaneously with –AIN for true differential acquisition. |
| –AIN (2) | Differential analog input negative | Enables common-mode noise rejection; voltage must stay within AVDD/AGND rails. |
| VREF (3) | Internal reference output | 2.500 V ±20 mV; buffered, factory-trimmed; drives internal DAC via 1.638× gain stage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit, medium-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7892BRZ-1 | 12-bit, 1.25 Msps, but uses internal reference only (no external ref option); higher 100 mW power; SOIC-24 package. | Lacks differential inputs and CMRR - unsuitable for noisy industrial sensor interfaces requiring common-mode rejection. | Choose AD7892BRZ-1 only when board space is constrained (24-pin vs 28-pin) and differential input is not required. |
| MAX1166BCAP+ | 12-bit, 1 Msps, SPI interface (not parallel); 3.3 V only; integrated reference; 20-pin TSSOP. | No parallel bus or BUSY signal - incompatible with legacy µP/DSP parallel interfaces; lower speed limits real-time control use. | Select MAX1166BCAP+ for new compact designs with SPI masters and where 1 Msps suffices; avoid for existing parallel-data systems. |
Compared with AD7892BRZ-1 and MAX1166BCAP+, the LTC1415CG#TRPBF uniquely combines parallel µP interface, true differential inputs, selectable reference mode, and ultra-low shutdown current - making it optimal for upgrade paths in legacy DAQ systems and noise-sensitive embedded imaging.

FAQ
What is the operating temperature range for the LTC1415CG#TRPBF?
The LTC1415CG#TRPBF is specified for commercial-grade operation from 0°C to 70°C. This is indicated by the "C" suffix in the part number and confirmed in the Absolute Maximum Ratings table. It is not rated for industrial (–40°C to +85°C) or extended temperature ranges - those require the LTC1415IG or LTC1415ISW variants. Thermal derating applies above 70°C ambient.
Does the LTC1415CG#TRPBF support external reference operation?
Yes, the LTC1415CG#TRPBF supports both internal and external reference configurations. When an external reference is applied to the VREF pin (with REF COMP bypassed), the internal 2.500 V reference is overridden, and the external voltage is amplified 1.638× to set the full-scale input range. This allows flexible scaling - for example, using a 2.048 V reference yields a 3.35 V full-scale range.
How does the Nap mode differ from Sleep mode in the LTC1415CG#TRPBF?
In Nap mode (SHDN = low, NAP/SLP = high), the LTC1415CG#TRPBF draws ~2.3 mA and wakes in 200 ns - ideal for burst-mode acquisition. In Sleep mode (SHDN = low, NAP/SLP = low), current drops to 1 µA but wake-up requires 10 ms - suited for infrequent measurements. Both preserve register state; neither resets the internal reference or clock.
Can the LTC1415CG#TRPBF interface directly with 3 V logic systems?
Yes, the LTC1415CG#TRPBF supports direct 3 V logic interfacing via the OVDD pin (Pin 26). When OVDD is tied to 3 V (and not shorted to DVDD/AVDD), all digital outputs (D11–D0, BUSY, RD) swing between 0 V and 3 V, meeting 3 V logic thresholds without external level shifters - verified by VOH ≥ 2.4 V and VOL ≤ 0.4 V specs at IO = ±160 µA.
What is the significance of the 60 dB common-mode rejection ratio in the LTC1415CG#TRPBF?
The 60 dB common-mode rejection ratio (CMRR) in the LTC1415CG#TRPBF ensures that noise or interference appearing equally on +AIN and –AIN - such as ground-loop voltages or EMI coupling - is attenuated by 1000× before digitization. This is measured DC to 1 MHz and enables reliable signal capture in electrically noisy environments like motor drives or industrial PLCs without added filtering.
