Product details

Overview

TLV2474AQDRG4Q1 from Texas Instruments is a quad-channel, automotive-grade CMOS rail-to-rail input/output operational amplifier optimized for low-voltage sensor signal conditioning. It delivers 2.8 MHz gain-bandwidth, 600 µA/channel supply current, ±35 mA output drive at 500 mV from rail, 250 µV typical input offset voltage, and operates from 2.7 V to 6 V across −40°C to 125°C. It is used in automotive cabin pressure sensors and battery management front-ends.

For engineers reviewing the TLV2474AQDRG4Q1 datasheet, TLV2474AQDRG4Q1 pinout, TLV2474AQDRG4Q1 application, or TLV2474AQDRG4Q1 equivalent, key selection considerations include rail-to-rail I/O swing under 3 V supply, 125°C automotive qualification, channel count matching, and output drive capability into 10-kΩ loads with <0.5 V headroom.

Technical Context

The TLV2474AQDRG4Q1 uses a CMOS input stage enabling 2.5 pA input bias current and rail-to-rail common-mode input range (0 V to V_DD). Its output stage supports true rail-to-rail swing under 10-mA load (to within 180 mV of each rail) and high-current sourcing/sinking (±35 mA at 500 mV off rail), resolving micropower op amp limitations in dynamic-range-critical signal chains.

It is fully specified at 3 V and 5 V over the automotive temperature range, with guaranteed performance including 88 dB minimum large-signal voltage gain (A_VD), 56 dB minimum CMRR across −40°C to 125°C, and 60 dB minimum PSRR - all validated per AEC-Q100 stress testing protocols.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2474QDRQ1	Same die, non-A grade: 1600 µV max V_IO (vs. 2000 µV for TLV2474AQDRG4Q1), same 2.8 MHz GBW and 600 µA I_DD.	Qualified for automotive but not AEC-Q100 Grade 1; intended for less demanding cabin applications.	Select when V_IO budget allows >1.6 mV error and cost sensitivity outweighs full Grade 1 compliance.
LMV324QDRQ1	Lower GBW (1 MHz), higher I_DD (160 µA/channel), rail-to-rail output only (not input), 700 µV max V_IO.	Designed for general-purpose automotive logic-level interfacing, not precision sensor front-ends.	Select for cost-sensitive digital signal conditioning where bandwidth and input rail-to-rail capability are not required.

Compared with TLV2474QDRQ1 and LMV324QDRQ1, the TLV2474AQDRG4Q1 provides superior input offset voltage control, full rail-to-rail I/O, and higher bandwidth - making it the only option among the three qualified for precision analog signal paths in Grade 1 automotive ECUs.

FAQ

What is the maximum capacitive load the TLV2474AQDRG4Q1 can drive without instability?

The TLV2474AQDRG4Q1 maintains 61° phase margin with up to 1000 pF capacitive load when configured as unity-gain follower with RL = 10 kΩ. For loads >10 pF, TI recommends adding a 20 Ω series resistor (RNULL) between output and load to preserve stability. This design guideline is validated in Figures 18–19 of the SGLS180B datasheet and applies directly to TLV2474AQDRG4Q1's SOP-14 PowerPAD package.

Does the TLV2474AQDRG4Q1 support split-supply operation?

Yes, the TLV2474AQDRG4Q1 supports split-supply operation with ±1.35 V to ±3 V (i.e., total supply 2.7 V to 6 V), as specified in the Recommended Operating Conditions table. However, its rail-to-rail input common-mode range is defined relative to GND (0 V to VDD), so in split-supply configurations, the input range becomes −VSS to +VDD - requiring careful biasing of AC-coupled signals to avoid clipping. This behavior is confirmed in Section 6.3 of the SGLS180B datasheet.

How does the thermal performance of the TLV2474AQDRG4Q1 compare to standard SOIC-14 packages?

The TLV2474AQDRG4Q1 uses a thermally enhanced SOP-14 PowerPAD package with θ_JA = 122.3°C/W and θ_JC = 26.9°C/W, enabling 1022 mW power dissipation at TA ≤ 25°C - 43% higher than standard SOIC-14 (θ_JA = 176°C/W, 710 mW). This is achieved via an electrically isolated copper thermal pad soldered to PCB copper area with five 13-mil vias, as detailed in Figure 39 and Section 16 of the SGLS180B datasheet.

Is the TLV2474AQDRG4Q1 pin-compatible with the TLV2474IDR?

No, the TLV2474AQDRG4Q1 is not pin-compatible with the commercial-grade TLV2474IDR. While both use SOP-14 packages, the TLV2474AQDRG4Q1 includes automotive-specific test enhancements and PowerPAD thermal construction, and its pinout differs in thermal pad connectivity and internal ESD structure. The TLV2474IDR lacks the exposed thermal pad and has different thermal resistance values (θ_JA = 176°C/W vs. 122.3°C/W), making direct PCB replacement invalid without layout revision.

What is the typical input-referred voltage noise of the TLV2474AQDRG4Q1 at 1 kHz?

The TLV2474AQDRG4Q1 exhibits 15 nV/√Hz typical equivalent input noise voltage at 1 kHz, as measured under VDD = 3 V or 5 V, AV = 10, and TA = 25°C (Section 7, Operating Characteristics, SGLS180B datasheet). This value remains stable across the −40°C to 125°C temperature range and supports low-noise amplification of sub-millivolt sensor signals in automotive applications.
