Product details
Overview
TLC2272AMDRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier designed for precision signal conditioning in low-power, high-impedance sensor interfaces. It delivers 2.25 MHz gain-bandwidth, 3.6 V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, ≤950 µV input offset voltage (max), and operates from ±2.2 V to ±8 V supplies - enabling accurate analog front-end performance in battery-powered transducer systems.
For engineers reviewing the TLC2272AMDRG4 datasheet, TLC2272AMDRG4 pinout, TLC2272AMDRG4 application, or TLC2272AMDRG4 equivalent, key selection criteria include rail-to-rail output swing, sub-1 pA input bias current, low-noise small-signal amplification, and Q-grade automotive temperature range (–40°C to +125°C) compliance.
Technical Context
The TLC2272AMDRG4 uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low input offset voltage (≤950 µV). Its fully differential input stage supports common-mode input voltage down to VDD−, making it suitable for single-supply sensor interfacing with ground-referenced signals.
It features unity-gain stable operation with 52° phase margin and 10 dB gain margin under 10 kΩ load and 100 pF capacitive load, ensuring robust closed-loop performance without external compensation in standard configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide industrial and automotive supply rails including ±5 V and ±3.3 V systems |
| Gain-Bandwidth Product | 2.25 MHz - enables stable amplification of signals up to ~200 kHz at gain = 10 |
| Slew Rate | 3.6 V/µs - supports fast settling for dynamic sensor outputs and DAC buffering |
| Input Offset Voltage | ≤950 µV max at TA = 25°C - ensures <0.1% error in 1 V full-scale precision measurement paths |
| Input Bias Current | 1 pA typical - preserves signal integrity when amplifying from >1 GΩ sources (e.g., piezoelectric sensors) |
| Voltage Noise Density | 9 nV/√Hz at f = 1 kHz - provides low-noise amplification critical for microvolt-level sensor signals |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A - rail-to-rail swing supports full dynamic range into ADC or downstream stage |
| 2 | IN− A | Inverting input of Channel A - high-impedance node (10¹² Ω) minimizes loading on feedback networks |
| 3 | IN+ A | Non-inverting input of Channel A - accepts signals down to VDD−, enabling true single-supply operation |
| 4 | VDD−/GND | Negative supply or ground reference - shared return path for both channels; must be low-impedance |
| 5 | IN+ B | Non-inverting input of Channel B - independent high-Z input for dual-channel signal conditioning |
| 6 | IN− B | Inverting input of Channel B - supports standard op-amp configurations (inverting, non-inverting, diff-amp) |
| 7 | OUT B | Amplified output of Channel B - electrically isolated from OUT A; no crosstalk specified |
| 8 | VDD+ | Positive supply - supplies both amplifiers; IDD = 2.4 mA typ at ±5 V enables low-power system design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher supply current (1.2 mA/ch vs. 2.4 mA total), lower GBW (2.3 MHz), same Q-temp rating | Better suited for ultra-low-power, lower-speed sensor buffering where 1.2 mA per channel is acceptable | Select TLV2432IDR if system prioritizes per-channel current efficiency over dual-channel integration density |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, higher cost, 360 µA/ch supply current | Required for microvolt-level DC stability in precision weigh scales or laboratory instruments | Select OPA2333AIDR only when sub-µV offset drift over temperature is mandatory; TLC2272AMDRG4 offers better noise and speed at lower cost |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2272AMDRG4 delivers superior noise performance (9 nV/√Hz vs. 25 nV/√Hz and 5.5 nV/√Hz respectively) and higher slew rate (3.6 V/µs vs. 0.16 V/µs and 0.15 V/µs), making it optimal for dynamic sensor signals where accuracy and bandwidth coexist.

FAQ
What is the maximum operating temperature range for the TLC2272AMDRG4?
The TLC2272AMDRG4 is qualified for operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 2 (Q-level) requirements for automotive electronics. This rating is confirmed in Section 6.3 of the SLOS190H datasheet under Recommended Operating Conditions for Q-level parts, and applies to the SOIC-8 (D) package variant.
Does the TLC2272AMDRG4 support true rail-to-rail input operation?
The TLC2272AMDRG4 supports rail-to-rail *output* swing but not full rail-to-rail *input*. Its common-mode input voltage range extends to VDD− (the negative rail), but stops 1.5 V below VDD+ - e.g., at ±5 V supply, VICR spans –5 V to +3.5 V. This is documented in Table 6.5 and 6.6 under VICR specifications for TLC2272A devices.
What is the typical supply current consumption of the TLC2272AMDRG4 at ±5 V?
At ±5 V supply and TA = 25°C, the TLC2272AMDRG4 draws 2.4 mA typical supply current (IDD), as specified in Section 6.6 "TLC2272 and TLC2272A Electrical Characteristics VDD± = ±5 V" of the SLOS190H datasheet. Maximum IDD is 3 mA across the full temperature range.
Can the TLC2272AMDRG4 drive a 10 kΩ load with minimal distortion?
Yes - the TLC2272AMDRG4 achieves 0.0011% THD+N at 20 kHz with VO = ±2.3 V into RL = 10 kΩ (Section 6.6), confirming clean signal delivery to standard impedance loads. Its 3.6 V/µs slew rate and 52° phase margin ensure stability without external compensation under these conditions.
Is the TLC2272AMDRG4 pin-compatible with the standard TLC2272 series?
Yes - the TLC2272AMDRG4 uses the industry-standard SOIC-8 (D) package with identical pinout to TLC2272, TLC2272A, and TLC2272M variants. Pin configuration is defined in Section 5 "Pin Configuration and Functions" of SLOS190H, and all share the same 1OUT/1IN−/1IN+/VDD−/VDD+/2IN+/2IN−/2OUT layout.
