What are the key features of TLC2252CPWRG4?
- Rail-to-rail input and output enabling full signal swing on a single 3 V to 16 V supply
- 0.06 nA maximum input bias current at 25°C for high-impedance sensor signal conditioning
- Dual amplifier in TSSOP-8 package reducing PCB footprint in space-constrained portable designs
What is TLC2252CPWRG4 used for?
TLC2252CPWRG4 is suited for dual-channel sensor signal conditioning in portable medical devices and wireless sensor nodes where micropower consumption and rail-to-rail output swing are both required. Its 1.75 mV maximum input offset supports 12-bit to 14-bit ADC front ends without trimming. The TSSOP-8 package and tape-and-reel availability in the G4 suffix streamline high-volume automated assembly.

Frequently Asked Questions
How does the rail-to-rail output of TLC2252CPWRG4 benefit ADC input stage design on a 3.3 V single supply?
With rail-to-rail output on a 3.3 V supply, TLC2252CPWRG4 can swing output voltage from near 0 V to near 3.3 V, matching the full input range of a 3.3 V ADC directly. This eliminates the level-shift or voltage clamp circuits that non-rail-to-rail amplifiers require, reducing component count and saving board space in battery-powered data acquisition designs.
What input bias current specification makes TLC2252CPWRG4 suitable for pH sensor or ion-selective electrode interfaces?
TLC2252CPWRG4 specifies 0.06 nA maximum input bias current at 25°C. Across a 1 GΩ pH electrode source impedance, this introduces less than 0.06 mV of bias-induced voltage error, well within the resolution needed for 14-bit pH measurements. Bipolar op-amps with 50 nA to 100 nA bias currents would introduce 50 mV to 100 mV offsets across the same source impedance.
How do the dual amplifiers in one TLC2252CPWRG4 package help reduce BOM count in a two-axis inclinometer design?
A two-axis inclinometer requires one amplifier per axis to buffer and scale the capacitive sensor output. Using TLC2252CPWRG4's dual 8-pin TSSOP package consolidates both channels into a single part, halving the op-amp component count versus two single-channel devices. The 75 dB minimum CMRR and 1.75 mV offset also ensure adequate accuracy across the typical ±90° measurement range.
