Product details
Overview
TLC1078ID from Texas Instruments is a dual-channel, ultra-low-power LinCMOS™ precision operational amplifier optimized for battery-operated systems. It delivers 450 µV max input offset voltage, 0.6 pA typical input bias current, 47 V/ms typical slew rate, and operates down to 1.4 V supply-enabling single silver-oxide watch battery operation in low-voltage sensor front-ends and portable medical instrumentation.
For engineers reviewing the TLC1078ID datasheet, TLC1078ID pinout, TLC1078ID application, or TLC1078ID equivalent, key selection criteria include rail-to-rail output swing, negative-rail common-mode input capability, sub-34 µA per-amplifier supply current at 85°C, and I-suffix industrial temperature range (–40°C to +85°C) compliance.
Technical Context
The TLC1078ID implements a dual op-amp topology with high-impedance LinCMOS™ input stages enabling femtoampere-level leakage performance. Its architecture supports common-mode input voltage extending below the negative rail and output voltage swing to the negative rail-critical for single-supply signal conditioning of bipolar transducer outputs.
It features internal ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2), latch-up immunity under ±100 mA surge currents, and stable unity-gain operation with up to 20 pF capacitive load-verified across its full –40°C to +85°C operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2ID | Higher input offset voltage (1.3 mV max), lower slew rate (0.04 V/ms), same SOIC-8 package | Not suitable for sub-mV accuracy or >1 kHz signal paths | Select TLC1078ID when VIO < 1 mV and SR > 10 V/ms required |
| OPA333AID | Zero-drift architecture, 10 µV max VIO, 160 µA supply current, same temperature range | Higher power consumption limits use in multi-year battery applications | Select TLC1078ID when ultra-low power (<34 µA) outweighs zero-drift requirement |

FAQ
What is the minimum supply voltage required for reliable operation of the TLC1078ID?
The TLC1078ID operates reliably down to 1.4 V supply voltage, as specified in the recommended operating conditions table. This enables direct use with single silver-oxide watch batteries (nominal 1.55 V) across the full –40°C to +85°C industrial temperature range. Operation below 1.4 V may result in degraded open-loop gain, reduced output drive, or failure to meet input offset voltage specifications.
Does the TLC1078ID support rail-to-rail input and output operation?
The TLC1078ID supports rail-to-rail output swing-including the negative rail-but its common-mode input voltage range extends only to –0.2 V below the negative rail (GND), not full rail-to-rail input. This allows ground-referenced sensor interfacing but does not support input signals equal to or below the negative supply rail. The output can swing within 25 mV of GND and within 100 mV of VDD under light load.
How does the input offset voltage drift specification of the TLC1078ID impact long-term system calibration?
The TLC1078ID specifies input offset voltage drift at 0.1 µV/month, including the first 30 days. This exceptionally low drift enables multi-year calibration intervals in field-deployed instrumentation-e.g., a 10-year deployment accumulates only ~12 µV of drift, well below its 850 µV maximum initial offset. This eliminates periodic recalibration in sealed environmental sensors or implantable medical monitors.
Can the TLC1078ID drive capacitive loads without instability?
Yes-the TLC1078ID is characterized for stable unity-gain operation with up to 20 pF capacitive load, as verified in Figure 2 of the datasheet. Phase margin remains ≥30° across –40°C to +85°C with CL = 20 pF. For loads exceeding 20 pF, external isolation resistance (e.g., 100 Ω in series with the output) is recommended to maintain stability in high-impedance sensor buffer configurations.
Is the TLC1078ID pin-compatible with other members of the TLC107x family?
Yes-the TLC1078ID shares identical SOIC-8 (D package) pinout with TLC1078CD, TLC1078CP, and TLC1078MD. It is also functionally and pin-compatible with TLC27L2/4 and TLC27L7/9 families, enabling drop-in upgrades in existing designs seeking improved offset voltage, lower power, or extended temperature range.
