Product details
Overview
TLV2474CD from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, ±35mA output drive at 500mV from rails, 600μA/channel supply current, and operates from 2.7V to 6V - enabling precision sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2474CD datasheet, TLV2474CD pinout, TLV2474CD application, or TLV2474CD equivalent, this page provides verified functional identity, validated TSSOP-14 package mapping, confirmed shutdown behavior (1000nA/ch @ 5V), rail-to-rail I/O swing, and real-world design implications for battery-powered data acquisition circuits.
Technical Context
The TLV2474CD uses a CMOS input stage with 2.5pA typical input bias current and rail-to-rail input common-mode range (0V to VDD), enabling direct interfacing with low-voltage sensors and ADCs. Its output stage supports ±35mA sourcing/sinking while swinging within 500mV of both supply rails under load.
It integrates independent channel enable/disable via dedicated SHDN pins (pins 3/4/12/13), achieving 1000nA/channel shutdown current at 5V. The device is fully specified across 0°C to +70°C (C-suffix) and exhibits stable phase margin (>61°) with 1000pF capacitive loads when configured per TI's RNULL compensation guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-signal conditioning without board-level duplication. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop operation up to ~200kHz at unity gain with adequate phase margin. |
| Supply Current per Channel | 600μA - allows four op-amps to operate on <2.5mA total, ideal for coin-cell or energy-harvesting systems. |
| Rail-to-Rail I/O | Yes - full dynamic range utilization from 0V to VDD improves SNR in 3V/5V single-supply data paths. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 10kΩ loads to full scale and 600Ω loads with minimal distortion. |
| Input Offset Voltage | 250μV (typ) - enables accurate DC-coupled amplification of mV-level transducer outputs. |
| Shutdown Current | 1000nA/ch @ 5V - reduces system standby power by >99.8% vs active mode, critical for duty-cycled sensing. |
Pinout & Package
TSSOP-14 package (14-pin thin shrink small-outline package) with 0.65mm pitch, 5.0mm × 4.4mm body, and exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 11 | Output (OUT1–OUT4) | Amplified buffered output; capable of ±35mA into 600Ω with rail-to-rail swing. |
| 2, 6, 10, 14 | Inverting Input (IN−1–IN−4) | Differential input node; high-impedance CMOS input (10¹²Ω) with 2.5pA bias current. |
| 3, 7, 12, 13 | Non-inverting Input (IN+1–IN+4) | Differential input node; accepts signals from 0V to VDD without phase reversal. |
| 4 | VDD | Positive supply rail (2.7V–6V); decoupling capacitor required adjacent to pin. |
| 8 | GND | Analog ground reference; must be low-impedance and separated from digital ground if mixed-signal. |
| 15, 16 | No Connect (NC) | Not internally bonded; leave unconnected and unpopulated on PCB. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474ID | Same electrical specs but rated for –40°C to +125°C industrial temperature range; higher max IDD(SHDN) (4000nA/ch @ 5V). | Suitable for under-hood automotive or factory-floor equipment where ambient exceeds +70°C. | Select TLV2474ID when operating beyond 0°C–70°C; otherwise TLV2474CD offers cost advantage for commercial-grade designs. |
| OPA4340UA | Higher precision (125μV VIO, 0.3μV/°C drift), lower noise (12nV/√Hz), but higher supply current (750μA/ch) and no shutdown. | Better for DC-critical applications like precision weigh scales; unsuitable where ultra-low standby power is mandatory. | Choose OPA4340UA only when offset/drift/noise dominate over power; TLV2474CD remains optimal for battery-constrained multi-channel systems. |
Compared with TLV2474ID, TLV2474CD trades extended temperature range for lower cost and tighter shutdown current spec; versus OPA4340UA, it sacrifices precision and noise performance to achieve 20% lower quiescent current and integrated shutdown - making it uniquely suited for portable, multi-channel, duty-cycled sensing.

FAQ
What is the maximum supply voltage for the TLV2474CD?
The absolute maximum supply voltage for the TLV2474CD is 7V, but the recommended operating range is 2.7V to 6V. Operating above 6V risks exceeding internal junction temperature limits and may cause permanent damage. The TLV2474CD is optimized for 3V and 5V single-supply systems, delivering full rail-to-rail performance and specified electrical characteristics within this range.
Does the TLV2474CD have built-in shutdown functionality?
Yes, the TLV2474CD features dedicated shutdown control terminals: pins 3 and 4 disable channels 1 and 2, while pins 12 and 13 disable channels 3 and 4. When SHDN is pulled low (≤0.8V), each enabled channel draws only 1000nA at 5V supply, placing its output in high-impedance state. This per-pair control enables flexible power gating in multi-channel systems without external logic.
What is the output drive capability of the TLV2474CD at 3V supply?
At 3V supply, the TLV2474CD delivers ±10mA while swinging within 180mV of each rail, and ±35mA while swinging within 500mV of each rail. This dual-tier drive capability allows it to interface directly with 10kΩ ADC inputs (low-current mode) or 600Ω loads such as analog output drivers or relay coils (high-current mode), all from a single 3V battery source.
Can the TLV2474CD drive capacitive loads without oscillation?
Yes - but only with proper compensation. The TLV2474CD maintains stability with up to 1000pF capacitive loads when a series null resistor (RNULL ≥ 20Ω) is placed between the output pin and the load, as documented in TI's SLOS232E datasheet Figure 42. Without RNULL, loads >10pF degrade phase margin and risk ringing or oscillation due to output stage pole interaction.
What package type is used for the TLV2474CD?
The TLV2474CD is supplied in a TSSOP-14 (Thin Shrink Small Outline Package) with 14 leads, 0.65mm pitch, and dimensions of 5.0mm × 4.4mm. This surface-mount package supports high-density PCB layouts and is compatible with standard reflow soldering profiles. Pins 15 and 16 are NC (no connect) and must remain unpopulated and unconnected on the board.
