Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Same SOIC-14 package; wider offset voltage (10 mV max) and higher noise (18 nV/√Hz only in PS/NS packages; 37 nV/√Hz in others) | Specified for 0°C to 70°C only; lacks extended EMI filtering and HBM ESD rating (2 kV vs 1.5 kV) | Lower-cost option for non-critical commercial audio or benchtop instrumentation where full temp range and EMI immunity are not required |
| OPA4134UA | Higher precision: 0.5 mV max offset, 8 nV/√Hz noise, 20 V/μs slew; SOIC-14; ±2.25 V to ±18 V supply | Optimized for ultra-low-noise audio; no output short-circuit protection; higher quiescent current (4 mA/ch) | Preferred for premium audio gear requiring lowest possible noise floor and distortion; requires external current limiting if short-circuit exposure is possible |

FAQ
What is the maximum operating temperature range for TL074ACDRG4?
The TL074ACDRG4 is rated for operation from 0°C to 70°C ambient temperature. This commercial-grade specification aligns with the "C" suffix in its part number and is confirmed in Section 5.3 of the TI datasheet under Recommended Operating Conditions. It is not rated for extended industrial (–40°C to +85°C) or automotive (–40°C to +125°C) temperature ranges - those require TL074I or TL074H variants respectively. Always verify thermal derating when operating near maximum ambient limits.
Does TL074ACDRG4 support single-supply operation?
Yes, TL074ACDRG4 supports single-supply operation from 4.5 V to 40 V total supply voltage. Its common-mode input range extends to VCC+, allowing input signals referenced to ground or mid-rail without level shifting. However, output swing is not rail-to-rail: typical headroom is 115–210 mV from each rail under 10 kΩ load. For true single-supply applications requiring full-scale output, consider adding a DC bias network or using a rail-to-rail output op-amp instead.
What is the input offset voltage specification for TL074ACDRG4?
The TL074ACDRG4 has a maximum input offset voltage of 3 mV at 25°C, with typical value of 1 mV. This parameter is specified in Section 5.8 of the TI datasheet under Electrical Characteristics (DC) for TL07xC-grade devices. The "A" grade denotes improved initial offset over standard "C" grade (10 mV max), making TL074ACDRG4 suitable for precision DC-coupled applications like active filters and sensor amplifiers where offset-induced errors must be minimized.
Can TL074ACDRG4 drive capacitive loads directly?
TL074ACDRG4 is characterized for stable operation with up to 20 pF capacitive load in unity-gain configuration, as shown in Figure 5-23 and 5-24 of the datasheet. Driving larger capacitive loads (e.g., long cables or ADC input capacitance >50 pF) may cause peaking or oscillation. To maintain stability, add a small series resistor (10–100 Ω) between the op-amp output and the capacitive load, or use a dedicated buffer stage. Do not rely on internal compensation to stabilize heavy capacitive loads.
Is TL074ACDRG4 pin-compatible with other TL074 variants?
Yes, TL074ACDRG4 is pin-compatible with all TL074x variants in the SOIC-14 (D) package, including TL074CDR, TL074IDR, and TL074H. Pin functions match Table 4-6 in the datasheet: pins 1–3, 5–7, 9–10, 12–14 serve identical roles across grades. The "G4" suffix indicates green (lead-free/RoHS-compliant) packaging but does not affect pinout or electrical compatibility. Always confirm supply voltage and temperature range suitability before substitution.
