What are the key features of TLC2652AC-8DG4?
- Chopper stabilization technique achieves 2.35 µV maximum input offset voltage for ultra-precision DC signal amplification without trimming
- 120 dB minimum CMRR (140 dB typical) enabling rejection of common-mode noise in differential measurement circuits
- 0.1 pA (0.0001 µA) maximum input bias current allowing use with high-impedance sensors and long-term integrator circuits
What is TLC2652AC-8DG4 used for?
The TLC2652AC-8DG4 is designed for precision instrumentation amplifiers, thermocouple signal conditioning, and bridge sensor readout circuits where DC offset drift below 1 µV/°C is critical. Its chopper stabilization eliminates flicker noise below 1 Hz, making it ideal for low-frequency strain gauge, load cell, and pH sensor amplification in industrial measurement systems. The SOIC-8 package enables compact PCB layouts in data acquisition modules and medical diagnostic equipment requiring stable long-term accuracy.

Frequently Asked Questions
What offset voltage specification makes the TLC2652AC-8DG4 suitable for precision DC measurement designs?
The TLC2652AC-8DG4 achieves a maximum input offset voltage of 2.35 µV with chopper stabilization that continuously corrects drift, maintaining accuracy over temperature without manual trimming. This is approximately 10x better than standard precision op-amps with 25 µV offset, making it suitable for 16-bit and 18-bit ADC input amplifiers where even small offsets degrade full-scale accuracy.
How does the TLC2652AC's 120 dB CMRR benefit differential sensor measurements compared to standard op-amps?
The 120 dB minimum CMRR means common-mode interference, such as 50 Hz or 60 Hz mains hum, is attenuated by a factor of 1,000,000:1, allowing microvolt-level differential signals from thermocouples and Wheatstone bridges to be amplified without being overwhelmed by noise. Standard general-purpose op-amps typically specify only 80 dB to 90 dB CMRR, which may allow several millivolts of interference to appear at the output.
When should a designer choose the TLC2652AC-8DG4 over a low-offset bipolar op-amp for integrator circuits?
The TLC2652AC-8DG4's 0.0001 µA maximum bias current makes it preferable for integrator circuits with feedback capacitors of 1 µF or larger, where a bipolar op-amp's typical 100 nA bias current would charge the capacitor by 100 mV per second. The CMOS input stage essentially eliminates leakage-induced integration errors, allowing integration time constants of minutes rather than milliseconds.
What package does the TLC2652AC-8DG4 come in and how does it fit into standard SMT assembly workflows?
The TLC2652AC-8DG4 is housed in an 8-pin SOIC (R-PDSO-G8) package with a 1.27 mm lead pitch and approximately 6 mm x 5 mm body size. This is a standard SMT package compatible with automated pick-and-place and lead-free SAC305 reflow at 260°C peak, fitting into the same PCB footprints used by many industry-standard dual op-amps such as TL072 or LM358.
